OK I want to share some thoughts on this topic but before I do, here are a few caveats
1) I'm certainly no professional on how to set up the axe fx
2) Anyone who knows me from the U2GT forum will remember I have a tendency to prefer 'a bit of grit' in my U2 tones
3) Don't you just love how U2 geeks obsess over the tiny things
Anyways. So a few weeks ago, Two good friends (both of whom are excellent guitarists and far more expert than me) spent a day comparing tones. I was using Edo's presets and my friend had his axe fx loaded with his presets (I should explain that he plays in a fantastic U2 tribute from the UK) My summary was this.
For the cleaner tones that Olivier is referring to, there was no doubt that in the room on the day my friend's tones were cleaner, chimier and more 'classic U2' than Edo's presets were in my setup. And I think we three agreed they were 'better' (whatever that means)
That said, I think what we were comparing to in making this assessment was more the studio version or some 'idealised' version of these clean type tones.
Based on the last three tours that I've been to, I don't really hear the edge playing this very clean chimey tone (however beautiful it is.) IMHO Edo's tones are more like the live versions, certainly from the more recent tours that I have been to. They are a bit more gritty.
Not sure if this adds anything to the discussion other than the possibility that at the end of the day Its largely down to personal taste. I am really enjoying playing with Edo's presets. Out of the box they sound great to me.
As for the more exotic tones, then I just take my hat off to Edo. The wilder and more overdriven or effects laden tones are just stunning. In the I&e pack, the low e note in the outro of 'until the end of the world pack' is worth the purchase price alone
