PokerStars vs. UltimateBet (reload bonus)

I've turned a $25 deposit at UB and then a transfer to Stars into a little over $100 right now. Just slowly building myself a bankroll. I've been absolutely slaughtering the .1/.2 at Stars.
I'm kind of wanting to go back to UB right now though for the reload bonus. However, I'm slightly hesitant because the stakes jump from .05/.1 to .25/.50. How are the .25/.50 games there? Could I likely beat them with just 200BB?
