If I had the choice between 50W, 100W, and 150W versions of the same amp, I'd go for the 100W if the prices weren't radically different.
50W is plenty of power for any gig I'll ever play from here on out. When I've played outdoors, I've occasionally used a 100W, or two 50Ws. But I doubt I'll be doing that much.
However, the bigger amps have bigger, stiffer power supplies and (usually) bigger output transformers that translate into...well, just a bigger sound. When I played Marshalls, I always used 100W amps with two tubes pulled. Even at 50W, a 100W amp just sounds bigger.
Having said that, 150W is overkill as far as I'm concerned. Costs more, heavier, and I don't think that you get much in return - unless you're one of the very few that NEEDS that much power.
I had a Mark III Coliseum - it was Simulclass, so it was about 135W or so - and it was WAY louder than I ever needed.
