I've had both. Not at the same time and the Orange had V30's and the Bogner (Überkab), GB 25s. So my direct comparisons wouldn't have very solid basis. But in general, I feel that audibly, you're not gunna go wrong here either way. I loved every style of playing that's come out of each of those cabs. Clean, crunch and way, way beyond.
Aesthetically, you'll notice the grill cloth starts to sag and dip over time with regular playing and if you're giging, wear and tear noticeably shows up on that Orange tolex like a nasty little surprise when you get it home. I've had a lot of "When the hell did that happen?!" Moments - even as rugged as it feels at first. The Bogner's gunna hold up to a bit more. It's pretty tough. Not Mills tough. But it's solid. That's the only thing that kinda bugged me. But I'm kind of a freak about that sort of thing.
