Yep, it's a toss up. The G&L Tributes have been getting great reviews, and the pickups installed in the one you're looking at are supposed to be really good, too. The original pickups are nothing to sneeze at, either, as they are the same pups used in the USA models.
Squier has been putting out some fine guitars lately. The newer models I've played all sounded great.
If you can play 'em both, please do so and post your opinions!
