At present I own all four of these modellers. I did have a Quad Cortex previously, but I sold that to fund the Axe III. I still have solid memories of that device though, so I will opine somewhat on that.
I'll start with the Boss because that is the easiest - I don't really know why the amp modelling gets so much love on this device. I tried it thoroughly, and I couldn't get a single sound I liked. I tried it set to line/phones and recording mode, I also tried it with the output select set to 'user' which from what I could tell, fully disabled any output compensation so you get a full frequency amp sound. It still sounded lifeless to me. A huge shame, because I actually think the control features (assigns, internal wave pedal, midi assigments, etc) are very good on the Boss and having seamless preset changes complete with spillover is incredibly useful.
I feel a bit nickel and dimed by it considering they tell you there are a bunch of effects from the 500 series in there, but they're missing parameters. And you don't get everything. And this isn't a cheap device. It retails for £840 roundabouts, which is nothing to sniff at. I also don't like that you get one master delay block and one reverb block - pretty limiting when you play in an atmospheric cinematic post-rock band.
It is smaller and lighter than the Helix (and the FC12 controller!!!) and I had visions of putting it on a board with a few of my choice stomps, and controlling everything with midi. All in front of my amp. But alas.... I don't think I'm gonna bother.

So ... Kemper. Let's get this out of the way - I have a real love hate relationship with the Kemper. On the one hand, being able to have my amps and my tones all in one portable and lightweight box that I can carry from studio to studio and gig to gig... what's not to like? The problem is.... I have literally NEVER been able to get close enough to the real amps. Save the speeches... I've heard it all before. Everything from "you're doing it wrong" to "they sound exactly the same to me!" ... and fundamentally, I hear what I hear - the real amp will have very punchy and defined palm mutes, and even after refining the Kemper will have fuzzy, flubby, smeary palm mutes, that have some kind of noise akin to crossover distortion, over the top of them, that isn't really related to the notes you play. I can't stop hearing it since I was able to recognise it. Being a high-gain player, it really ruins my enjoyment of the unit.
Add to that the fact that if you put delays and reverbs in front of the amp like I do, then you lose spillover, which is a pretty big deal for me. Then you can only control two midi devices, and to this day I still find the workflow confusing - especially the performance mode. It just does not make sense to my brain, and I've been going round the houses with Kempers for 10 years now!!
Right now they seem to be focusing their development efforts on a bunch of stuff I don't care about - bad sounding double-tracking algorithms and iPad apps.... no thanks mate. It's entirely possible they will come out with a follow up unit that fixes all of the bad things. I wait with baited breath, but as I said in a thread I started previously - I've lost faith in the concept of profiling.

That brings me on to the Helix. I'll be honest straight up front - I love the Helix. I think it's amazing. I think it sounds great, has tons of features and options, and very little cruft. It is very streamlined and very well thought out. When it launched it was missing a ton of stuff that I wanted, but I got one anyway, and it has just gone from strength to strength. But if I'm honest... there is something about the amp modelling that doesn't grab me. I can't quite place it, much more difficult to identify what I don't like about it than with the Kemper. Sometimes it feels overgained, sometimes it feels undergained. Sometimes it feels fuzzy, and sometimes it's too spikey and choppy on the transient. And this is with the same amp at different gain settings! I don't fully grok it, but I don't always enjoy playing through the Helix amps.
The delays and reverbs are pretty damn good. They get a bad rep, but I've had them side by side with all the major Strymon pedals and Boss pedals and TC Electronic, as well as the AxeIII, and it really puts up a fight. Especially the newer reverbs like the Dynamic Hall. I don't always enjoy the default settings, but since they added favourites, that annoys me way less than it used to.
I remember when it launched a lot of people said that the dual path approach Helix took wasn't as good as the grid that the Axe took. To be honest, I can't think of a situation where it ever held me back. I also really appreciate that you can take the volume knob out of the signal path, and truly have a unity gain signal path if you want (ie: empty path A straight to the output is unity gain, before you put any blocks in)
There's something like 230 effects in the thing. Really impressive. Their design philisophy isn't the same as Fractals. Line6 are more about putting in that EXACT pedal... and limiting you to those EXACT controls and what not; whereas Fractal offer super deep craft-yer-own-tone possibilities. I really like both approaches.
Honestly, I'm struggling to think of anything bad to say about the Helix.... the one thing I will say is that the delays across the board have a tendency to "milk out" - they go a bit squishy and diffuse. Try getting 28 echoes out of the Simple Delay... it's actually quite difficult. On a Boss pedal, it's like.... oh.... 50% on the feedback knob.... there we go.
