Is there a music store near you? Take YOUR guitar to the store and play it through a bunch of amps. That is the ONLY way you will know how the amp will sound with your gear. Try a bunch and pick the one you like most.
Note that you don't need 150watts for bedroom stuff. If when you play live, you have a PA, even 50watts is fine. When you check the amps out, note that there's also a variety of technologies now: all-tube, tube preamp/solid-state power amp, and amp "modeling" which might have a tube preamp. Check out the speaker cabinet too before you buy. Check out the number of inputs/fx returns and make sure it will suit your purpose.
When you're in the store, play the amp at all volume settings - screaming loud, mid range, and low. Play it with different EQs. Get a sense of the scope of tones you can get.
