I play too many genres so the Helix has been a godsend. I only use like 3-4 different amp sims but I use a lot of different snapshot presets with different gain, compression, FX levels etc. for different situations that have really been worth the trouble. Before I had the Helix for live use I always had to use the JCM800 that every single venue/studio here has, and while it's not a bad amp at all there's only so much you can coax out of it without dragging along a substantial pedal board, and having to fiddle with amp settings mid-set was a huge pain in the ass.
