They are both pretty good.
The basic translations needed to better play the game are there in both patches.
You can see the exact specifications of each patches in their own respective threads to see if what you need has been translated or not.
so if you just need a basic menu, pokemon name, pokemon center, pokemart, etc translation (like me), both are fine.
Rabiq's inclusion of the freezing patch is not that much of a feature, you can download it and patch it yourself in 30 seconds, and you only need to do it once.
