It really depends on which one you do better.  Both can be almost unstoppable, but most people who aren't really skilled at foos have a tougher time with angles.  But......blazing speed is impossible to stop if you're faster than anyone else (I can beat just about anyone anytime with my push or pull shot when I'm on and fast).  So it really depends on your skill level with each.  And, to some extent, the skill level of your opponent(s).
