With that kind of stage volume I would not trust any budget combo. I own a TC BG250-208 and honestly, I've found it seriously underpowered. I play weekly in church with 2 - 3 acoustic guitars, a flute and a small synth that runs off its built-in speakers (I know, ... it's a poor church) with no PA support whatsoever. In that setting I have to crank the volume up halfway (to noon) to appropriately hear myself. I stand next to the amp which is on the floor but tilted up toward me. If I flip the bass and the amp input to active (I like to play it passive usually) I can get the volume down to maybe 10 o'clock but again, I'm up 'against' unamplified acoustic instruments and singing voices.
I also occasionally play with an oldies band where I've previously been using an ancient Peavey Basic 60 (50 W or so) on a combo stand at about waist level. At times I'd had to push it but I'd always heard myself well. In the same setting the TC can't make itself heard. I've recently bought a TC 12" extension cabinet (RS112) that allows me to get full power from the combo but I can stand next to the setup with the volume cranked to the max in my living room and the level is far from painful. And no, I don't have the active/passive switch in the incorrect position. I know amp and speaker W ratings do not translate to volume directly but 50 vs 250 (with the extension cab) should not be in the same league. With these setups they are and the 50 W Peavey may even come out on top.
