The 64-bit variant is currently not entirely bug free, but should theoretically offer better performance. ZOS will update the launcher at some point to automatically select the best executable for the system.
The most important difference is: A 64-bit application is capable of addressing more than 2GiB of RAM, the developers can use this to improve the games performance.
Yeah, I'm excited that there's a 64 Bit option, but when I manually launched the eso64.exe my FPS was sooo freaking bad, I know... I read that the 64 Bit client has framerate bugs and the devs here are working on it. Until then, I guess I'll stick to the usual 32 Bit gameplay and yeeeah... get those freezes once in a while. Derp.
