A) A watt's a watt
B) That said, to double the volume, you need 10x the watts (roughly).
C) As a tube amp gets closer to max power, the tubes start to distort in a musically pleasing way. When a solid-state gets close, it distorts in a non-pleasing way. So even though the 100t is 'only' 100 watts, it really starts sounding good when you push it. Some players (myself included) love the way it sounds, others want big, clean volume (hence the Super Bassman's 300 watts). You've got to try the 100t for yourself and see if it suits your style.
