Blooper is, in my opinion, a far superior looper. It’s seriously so good; has tons of character too. The “repeats” knob effectively sets the decay (while recording is engaged) and, yeah, having 8 layers gives one tons of flexibility.
Tensor is a real-time temporal mangler that can do short loops. NXT mode opens up some particularly wonderful short stuttery stuff.
I have both, and plan to keep both unless I just absolutely have to part with one or the other. But they’re both awesome, and different. Probably not what you wanted to hear
