I've been using the Axe-FX (ultra and now the II) for 4 years now. I go straight to PA and carry a midi pedal for switching patches when needed. I've gotten a lot better at dialing up sounds and it's not that hard to dial in a virtual effects chain that you need. There are endless possibilities and the next update looks pretty sweet. As far as variety, the Axe FX II has over 70 amp models, lots of IRs and the ability to create your own, Tone Matching - so you can capture any amp you like. 20 or so OD pedals, delay (analog and digital models), Chorus, Flange, Univibe, etc. etc. You would spend just as much getting your pedalboard in order with stand alone pedals.
