I guess most people choose regular tables to play poker ,althought it's slow , cause they control the action more , they choose the position/fishes they want to play with , they wait for the right time to play their good cards and get paid .
That's more profitable than zoom kind tables where you face on every table different opponents on different positions .
I play both .I play zoom when I need some vpps quickly or I am bored and want to play rush poker .
The good thing I see in micro zoom is that some fishes might call all in preflop , you have AA and they call you with AK or whatever hehe , in addittion it's good to try forming sets . But if you're not carefull very easy you can lose your stack on zoom tables .
