I own both. Woz hands down.
As Panzer said, just get a later build if your concerned about light boards (but still not a big deal IMHO)
Also depends on what kind of owner you are. if you tend to flip pins often, GB could be fun. But if you tend to keep them and really dive in Woz has soo much packed into it, that it wont get boring fast.
That's my .02
