LVL7 Wiz Tower vs. LVL2 X-Bow

I say wiz tower, Xbows r just archer towers with more range imo. Idk y ppl say they're amazing.
But then again I started this game 2 months ago

I'm the same and I'm doing 1 of each but wiz tower first

Wiz Tower. That's from a guy who upgraded both XBows to 3 before touching my L6 WTs or even getting the fourth WT past 3. The upgrade to WT it tremendous--effectively doubling the output against Archers (1-shotting L6 vs 2-shotting). Also very handy against loons and minions. The XBow upgrade, by comparison, is less exciting. Once all four WTs are up, then get the XBows straight to L3. After that I'd suggest Teslas.

EDIT: In case it's not clear, I think I made the wrong call and would do it differently next time.
