338 win mag or 325 wsm?

Which would you rather have, a 338 win mag (or the 338 RCM if your want compact for better comparison), or the 325 WSM. I know the 338 has alot more bullets to pick from for reloading, but I've heard the 325 is a slightly better cartridge, having the trajectory of a 300 WM and the hitting power of the 338. So which would ya pick?
