Best time to play?

Would be interesting to now when you guys think it's the best time to play small stakes hold'em. As a European I have never tried playing late nights and early mornings (that is between 8 pm to 2 am EST) so I can't have opinion about those hours. Do you think it's a big difference between different hours? I think European evenings are better than midday or afternoon. And does it depend on where you play, are some sites better than others during certain times?

Small stakes means 2/4 to 5/10. And best games (at least to me) is the loose ones.
