Sure, it's the only candidate because it's essentially the only anywhere near completed model we have. There is always Garret Lisi's E8 theory but it's got a lot of problems, for instance he needs to achieve some intricate symmetries between leptons and bosons which as many physicists say is not like adding apples and oranges but apples and thunderbolts.
I'm a huge fan of M-Theory, it's just more surprising and fascinating the more you learn about it, and there might just be some evidence for it in cosmology, depending on whether or not the phenomenon of Dark Flow is adequately confirmed - It was predicted by string theorists prior to turning up in the WMAP data, so that kind of predictive power impresses me immensely.
Another favourite of mine is the Holographic Principle, that really fucks with my head, I can't begin to comprehend it beyond it's description of black holes and even that is dense, but that applied to the entire universe, the thought that my 3D experience is a projection from a 2D vibrating surface encompassing the universe is truly mind boggling.
