Like you I only use 5 or 10 sounds and only a couple of effects but these effects nearly always need pedals and the hassle that goes with it ( power, patch leads etc). So glad I don't have to mess around with that stuff.
So I see the KPA as WAY more convenient over a valve amp. No messing with mikes, consistent sound and total sound control to give me an Ac30 to instantly switch to a Dual Rectifer etc...and all with 3 leads....
I sort of agree with option paralysis but it takes courage not to get dragged into it. what i like about the KPA is you can get a good sound almost instantly, but you can tweak endlessly if you want to...
I would never go back to a Valve amp due to hassle, weight, limitations etc.
Totally agree with that.
The alternative (to me) ist not a tube head + pedalboard, but a small board (think Iridium + Collider + drive pedal.) straight into mixer or foh. No more thinking about settings. Still, I just consider this...
