There are distinct forms of poker played online. These are cash games, also known as ring games, sit and go tournaments, and multi player tournaments.
These are not poker variants, but game formats.
As to which is the most profitable, that will depend on the players own style.
Some players will prefer to outlay small buy ins for large tournaments with big prize pools in the hope of hitting big some time, but willing to take the slow depletion of their bankroll until they do hit the jackpot.

Not every one is willing to risk their entire buy in at a no limit table which could all be lost on one hand.
So your own situation, temperament and bankroll will dictate which format best suits you. And all of them can be profitable if you play smart. Of course, ifyou are playing for a poker bonus offer it will also impact on which game you play.
Without a doubt, the most consistent game for making reasonable profits from poker has to be no limit holdem. While the massive payouts available for the bigger multi table tournaments could make you rich, you could also go broke long before you hit one of those.
The steady bankroll management inherent in sit and go tourneys is mirrored with a steady and predictable return too. And a profit cap is set depending on your stakes.
With no limit, you can double your buy in again and again in one session. And don’t forget that you can limit your losses by not rebuying if a table is not working out for you.
On the other side, if you buy in to any tournament format, and you do not make the money, then you lose your entire buy in. If you sit in to a no limit table and do not do so well, you can always cut your losses and retire for the evening, or change to a more suitable table.
If you don’t know which one is best for you, then the only real way to find out is to try them all.
