Based on the limited information about the OP that we are working with so far, I'd say the SS will be the safer choice with the greater chance of fully satisfying and delivering optimal performance.
The tube amp may be a good choice as well, but can't say for sure without more info as requested early on, so it seems riskier at this point to me.
