There'll be almost no chance to double up before you need to start push/fold, so it depends on how good you are at applying ICM compared to your average opponent. If ICM play is your strength (compared to your deep-ish stack play), then you should get more of an edge.

I play 6 man turbos - they're over quicker (20 mins to win, 15 mins on average) because they're both turbo and short-handed, but they actually play like a regular speed 10 man in the early levels because orbits are much quicker, cancelling out the turboness. Best of both worlds, for my preferred style of play anyway.
