What's your amp of choice?

I have a fender champion 40, might start playing at open mics with my band soonish, and want to upgrade. Looks like the Boss Katana's are highly regarded but I have a bunch of pedals now and don't really feel like I need all the extra amp FX. My budget is probably around $200-$400

What's your favorite amp to use with your pedals in that price range?
