Yes, but personally I avoid collision as test operator, simply because, if particles are fast, then they might be way over above collision, then in the next frame, way bellow collision op, so it won't detect them.
Then in order to to fix it, I would need to make TyFlow work to 1/2, or 1/4 timestep, which will make simulation twice or four time slower.
Surface test covers more space for detection, have much more options to control it (my favorite "surface inside"), and I never noticied it's any slower then collision operator.
Collision operator I mostly use only for... collisions.
