Try it once and you're fucking hooked. From than on your regular amp on its own will sound thin and lame in comparisson. You'll piss off the other guitarist in your band cause he'll sound thin and lame in comparisson as well.
My car, back, most spaces/stages,...are NOT accomodated for my glorious souding stereo rig
It sounds too good NOT to make it happen though, aside from the extra oomph, the ability to send loops/modulation to one amp, and dirt to the other, is just pure bliss.
