2nd one has a more slimmer neck and has humbuckers rather than mini humbuckers both are probably overpriced as well. and they certainly would kill a squier strat even though theyre overpriced

Both of them are way better than the squire strat.

The 2nd one has a flamed maple top, which is really really pretty and provides lots of eye candy.
2nd one also has humbuckers, whereas the first one has mini humbuckers.
