I prefer to play live. What do I know, it has another flavor.
The looks, the antics, the conversations with friendly players.
I have a problem, in my country in general the MTTs in places that are played are very expensive for me at least at this moment.
That's why I play online.
The advantages are for me to play online.
The MTTs are faster, at least I play maximum in 2 tables I only play MTT and SGN you have a bigger picture of the game (opponent stacks, table positions, position in the general table of the tournament, then the rest is the same.
I can also play tournaments at the time I have.
Cheers
