A lot of the same
For starters the Tornado and the Green are essentially the same boat with only a few very small differences. They both have the same rocker profile (line them up and you can essentially trace them) and virtually the same volume and width, which on a boat of that size doesn't matter hugely. The only diff. is that the green is a couple inches longer and the bow is slightly peaked to help with some speed. I've paddled both, and they both handle great, takes a bit to really figure out how to turn them easily but once you dial it in they turn on a dime, relatively to the fact that their huge. That in mind they are both great boats for almost anything, and you could prob pic up a tornado for a lot cheaper than a green so...
the remix 100 i've never paddled, but i have seen. looks like a great boat. looks like it'd be just a tad bit faster than the other 2 and may turn easier. but as I've said i don't know for sure, you may want to try and find someone who would be able to give a better review of it.
hope that helped a bit
