Was the Game Gear a great or bad handheld?

I'm going to wait for reviews on the Game Gear games before I try them out on the Virtual Console. The emulation is incredible and I think it's a great way for newcomers to experince an old system without actually having the system. Plus the games are as cheap as the Game Boy games which I think a long time ago they were more expensive.
