The Rubber Guard is the best guard system for MMA:

Rubber Guard:
- allows you to strike (elbows and punches)from bottom without being hit back;
- allows you to go for submission without worrying about getting hit;
- Worst case scenario it is a great stalling position, where you can hold someone down without any damage;
- great for sweeps (specially omoplata sweeps);

open guard:
- not so good against ground n pound;
- not so good for stalling;
- rarely you can get a sweep from it;
- no affective striking other than upkicks.

half guard:
- good for sweeps;
- not so good for stalling;
- not many submssions from there.
- not a good spot to try to strike

full guard:
- good for submissions;
- not so good for stalling;
- good for sweeps;
- not the best spot to try to strike back;

butterfly guard:
- nothing but a good position to work on sweeps and to work on your way up;
- not many subs;
- not the best position for stalling;
- no striking whatsoever.

ps: I’m talking about the use of these type of guard exclusively for mma.

do you guys agree?
