They both work, I tested them several times. The archives file names are long though it can sometimes mess up extraction.
But you want to get a clean copy of the game and tfpatchguy's patch and any extras you want. Either
2.5.2, or
3.0.22 the very
latest version of the game. Click the link to instructions for whichever you want.
The 3.0.22 one is only a WIP temporary patch, but it's very playable. 2.5.2 has had a lot of updates to polish it up. Both of them have extras bits the other haven't (for now anyway), saves can't be swapped between them.
