Differences between online poker sites.

Perhaps, this thread should be in "Poker Strategy", I don't know.

My comment, or question, is, assuming all players are the same skill level from site to site, do winning (best) hands tend to be more common based upon each site? Wait, that's confusing. What is the most common best hand on each different site?
I've been playing lots of NLHE freerolls mostly on FT. There I see lots of TpTk, 2pair, and flushes win.
Just started on Stars and Cake and see fewer TpTk wins, more 3ofakind,straights, and boats winning.
Is this just me, or do the cards seem to roll different on different sites?
When I play live ppK is stellar, on FT it almost is always busted by Arag.

Good hands are good hands everywhere, and a suckout is the same on any site. What you're describing sounds like chasers hitting the latter, which is not uncommon in freerolls, anywhere. How many hands are you basing your analysis on, from each site? I mean 100,1000,10000?

I play mostly FT, so 100k min there. PS and Cake under 10k. I agree, good hand is good hand, no matter where you play. I've also played alot of live games, casino and home. Live play seems so much slower and calculated play-wise that I never noticed what I see online. Again with FT overall, I see more flushes catch, whereas on PS and Cake in the short time I've played the board seems to suit up far less often. Another thing I've noticed recently on FT, and I am talking about FreeRolls, is that with the multitude of all-in situations very rarely will I see a player drawing dead after the turn, the river suck out seems possible far too often. Am I seeing patterns online that i never noticed live, and if so is that the norm online? Again, if so, what patterns have been noticed on other on-line sites?
