We're all different, I MUCH prefer the largest field sizes possible.
If I have a choice of a 200 player tournament or a 2000 player tournament, I will play the 2000 player tournament every time.
Because tournaments pay out a specific percentage of the field, it is NOT easier to cash the 200 player tournament than cash in the 2000 player tournament... you have to beat approximately 85% of the field in either tourney... Yes, of course that takes much longer with 2000 players, but so what? I am always prepared to play 6, 8 or even 10 to 12 hours in any tournament I play. By their very nature, tournaments are not a sprint, they are a marathon.
And naturally, when we DO make the money, the 2000 player tournament is going to pay out much more than the 200 player tournament does. That is a simple math exercise that no one would dispute (assuming equal buy-ins, of course).
So unless you are pressed for time, then always play the largest field size you can find... and if you ARE in a hurry, then you shouldn't be playing a tournament that day, you can either play a single-table Sit-and-Go, or play cash games.
My opinions obv, I know others disagree with my take on it.
