I went down the spark amp route for a while, everything is locked into their ecosystem.
Bought Bias FX so i could use hardware or software and get similar sound.
Dissaster on stage, the Bias FX locked up as it could not find its license over the internet, it was the last time I ever wanted software that requires an internet connection ( bye positivegrid and roland soundcloud)
Now use amplitude 5, I still use GR7 for presets, but IK A5 works well for me, I use a FCB1010 to control effects via midi, Amp sims are good but for me the big deal breaker was the reliable Midi mapping to the effects chain. and allowing both pre and post effects chains to the amp sims ( oh and good price 99 euros at the mo).
This allowed me the option of both presets per song part and pedal control of reverb chorus overdrive etc.
don’t get me wrong, some are great in a studio running in ableton but not live with GP.
