I've been using Jacket for a few years now, and in my mind, it's the best and most usable iTunes plug-in out there. Sure, it's not as fancy looking as JewelCase or even Front Row, but no other visualization plug-in let's you rate your songs in full screen mode.

Jacket may be basic looking, but it gives you everything you need; the CD cover enlarged to fill the screen, and artist, album and song info displayed in any font size you like. In preferences I set "Expand [CD cover] to fit window size" and "Reverse Black/White to make the background black. Then I use the font Helvetica Neue Black Condensed at 72 pt aligned to the left. That makes the best full screen view I've found.

The way I use Jacket, is using it in Full Screen mode on big screen TVs or monitors throughout my house. It's perfect to have the CD cover and song information displayed so large that you can easily see it across a big room. Then, by having a wireless bluetooth keyboard at hand, I can rate songs by pressing a number key while cooking or working out. Why no other plug-in can do this is a mystery...

My only gripe is that the Full Screen mode doesn't work properly the last year or so. I have several Macs, and have tried to find a pattern, but to no avail. Sometimes it works and sometimes it doesn't. Anyway, you can still use it, as the normal mode is maybe 90% of Full Screen. However, I would be very grateful if the programmer could fix this.

Thanks for a great plug-in!
