I Know here using Axe-Fx 2 we're few...
But how do you route the axe fxII for gigs?
Using poweramp?
yes
yes, front end for pedal & effects and or in an effects loop
Or just send directly for the PA?
yes
There is no "best" option, only one that works "best" for a specific bassist with specific needs for a specific situation. Personally, I use the AxeFx direct for everything: amp model, cab simulation, pedals, effects...the whole thing. Running into a Crown Power amp (mono) bi-amped into a full range speaker system (2 cabs, each with a Ciare 15" coaxial).
Ps: I wish Fractal Audio made more bass amp options... SVT is good, but 3 or 4 more options would be great hahaha
Yes, a number of people have also requested this. The AxeFx is a pricey solution for a bass preamp, but you get a lot of processors for the money (and a tuner). Replaced my SVT, and rack tuner, Sans Amp Bass Driver pedal, rack FX processor (G-Force) and rack compressor. My AxeFX based rig is more light weight and portable, and has much more flexibility of tone than my old rig ever had.
I can see where some bassists may not be able to justify the price tag, especially if all they need is a couple simple bass tones and their effects processing needs are few. But if you like to explore tones and like to expand into a variety of different sonic areas, then the AFX is the perfect tool. I highly recommend any of them, but the AFXII really kicks serious ass. Right now for me, the AxeFx is the ONLY tool that allows me the freedom to do just about anything I can think of with tone, dynamics processing, effects, and live pedal control of those tones/effects. Add USB recording functionality plus AxeEdit for ease of backups, loading cabinet IRs and firmware upgrades, and that puts it totally over the top JMO.
