J.K.
I've had both, and loooove the gel polish. It lasts exactly 4 weeks for me, every time. And it's always just peeled off all in one piece (not chipping or anything before that). It hasn't damaged my nails yet, but then again mine are pretty strong. They don't file or anything before they put on the gel.
I didn't like acrylics because it made my nails thicker and it bothered me for some reason. The gel wasn't thick, and it couldn't actually be filled. I wonder if there are different kinds of gel? the place I go to just says "gel polish" and it costs $25 and was basically like regular nail polish but under a UV light.
