Theano / Python / ugly summation: It’s a Python library that takes complicated computations and gives them to the CPU or GPU in a more efficient language. It is still about tensors and sounds a little like TensorFlow to me. Even the code kind of looks familar, due to being written in Python of course, but also because a library is being invoked to go do math.
Theano feels at this point less, I don’t want to say developed, but TensorFlow 1.0 certainly seems to have more going for it at the moment.
Torch / Lua / ugly summation: I don’t know anything about Lua, and that kind of packs sand in my bearings instead of grease. We’re still talking about a library that is geared toward computation heavy work. As much as I like the idea of community supported projects, they never quite feel as polished as something with a corporate logo floating - if silently - in the background. I would show some code using Torch, but it’s definitely different enough that I’m not comfortable digging into it enough to find some bit of code that makes sense to me. Not that it’s too dense for me to do that. I just feel like I would be wasting time on something I have no plans to dig into.

Why stay with TensorFlow?
For now, TensorFlow beat out PyBrain early on, and although Theano remains in the Python arena, I feel like I’ve already made some progress on learning about TensorFlow. Stopping at this point to learn about Theano would be giving in to some attention deficit and I’d rather avoid that. I certainly haven’t become even a beginning moderate expert at TensorFlow, I just think I’m satisfied that it’s a solid direction. Torch, I’m sure is a great library and is supported by a wonderful community, but again, I’m planting my feet on TensorFlow and will delve into learning about making it more accurate at identifying handwritten digits.
