I'm trying it right now. It seems to be the only one that I can find that offers a 5 column app drawer and allows resizable widgets for free.
It seems pretty fast, there is choppiness every now and then but that is usually when I'm running other stuff at the same time.
The biggest downside is the Honeycomb menu bar. I emailed the developer about this issue, hopefully they will take care of it since it is a fairly simple fix. If some of you like it too (except for the menu bar), I'd encourage you to email them and complain. The more complaints the higher the chances of a fix. email@example.com
