I just posted somewhere else on this topic.
Going into it, and I see some of you feel the same way, you can live without some of the effects and the Standard is enough. I decided to go the Ultra route. At first, Standard would have been enough, but then, just putting together a pair of reasonable rigs, I realized Ultra is barely powerful enough to really model the whole thing including room tone, eq, etc. I never had two rigs at the same time, so I didn't even imagine that as a concern going in. Now I see why the pros use multiple amps, they complement each other. And once you're on that path, and you want to maintain room tone and a hint of modulation, you're definitely talking Ultra.
