I actually don't mind the blown-out sun as much. It actually creates a line, in a way; the blown-out sun catches your eye, and you follow the light as it darkens, and it leads you right across the trees...
If it could've been just a little less, so that the branches didn't vanish into it, that would definitely have been better. But blocking the sun too much behind a tree, I think would almost ruin the effect I mention.
Granted, that's definitely a personal preference rather than anything else!
