People judge digital units mostly by their amp tone and forget that FX are also important. The world leading FX in an all in one package were the main reason I bought the FM9, besides its good amp tones, of course. I would not go as far as some (like tonewars or others on youtube) and say that with all the new capturing tech, modelling is already dead. Modelled amps still can sound very good and good sound will always remain good sound. I think this is the main point and not necessarily "accuracy". Not even two same amps sound exactly the same. But, yes, if you want total accuracy and a very special amp tone and feel that is unique (for you), you just want to go from sweet spot to sweet spot and just want to skip that (damn!) tweaking madness, there is no other way in the digital world than profiling/cloning/capturing (although with a good IR there is to need for tweaking any more).
At this point I would like to add one more thing that for me, personally, is the real next step in all in one units: real analog modelling will be introduced on June 25th with Bluguitar's AmpX. This will be the world's first multi fx pedalboard amp with zero latency. At least this is what it promises, among analog FX and "real" Amp tones, because it simply is a "real" amp. Do we "need" analog modelling? We will see, that's a different question that cannot be answered for everyone. But as an Amp1 owner (the best mini Amp I've played so far, no jokes), I, personally, am curious to the bone about the AmpX. If you know anything about Thomas Blug you can expect Amp tone greatness. But if you ask me: buy whatever you like, it will sound good in 2023. "Good units" won't cover shitty playing.
