I'm a guy (and the OP) and still found Tangled to be slightly better. Don't get me wrong, TS3 has an incredibly powerful final act. Once they escape from the day care, head to the incinerator, and get delivered to Bonnie, the film shines even brighter than some of the best Pixar moments they've ever created.
However, until it got to that point, I was a tiny bit bored. Not a lot, but a little.
TS3 is still an excellent movie -- a B+, in my opinon. Tangled just worked a little better for me in terms of story flow and (surprisingly) humor. It gets a slightly better A-. I must say that I do think part of the reason I enjoyed it a bit more is because I was expecting nothing. The commercials and previews didn't make it the least bit appealing to me. But, somehow or another, I was won over by the whole thing.
