I love it either way. But as someone who has done the organising, recruiting, DKP etc for 25 man versus 10 there is no comparison.
I actually enjoy the game a lot more in 10 man if I am leading because it's a lot less extra shit I have to do. From my pov a 25 man raid is he same for me as a player but miles more effort for me as a person. "Cat herding" and a desk full of post it notes with absences, lateness, who doesn't get on with who etc simply isn't all that fun.

Aye, personal preferences can be like that. Of course i'm not sure how wise it is to for you to extrapolate from your personal preferences to make a rule for all 2 million of wows raiders.
