If you're going for damage, defense, and resistance, swords' the way to go. Life leech and hit chance are archery, and the mage picks up mana drain/leech and spell damage (obviously). This is the extent of my knowledge in terms of Arkandian Explorer's base weapons.
I have to admit, even though you have to 'wait' to finish building alot of things, it's nice that you can always just buy what you need to keep playing with in game resources. This way active players can keep playing while casual players can play without missing anything. The only downside I've had in this entire game is that some of the fights seem to move really slowly, though I think that might even be something on my end, and not the game itself.
I found the best way to survive past level 100 is to build a ninja tower, a wizard tower, a cannon, a top tier bank, and then work on your first monkey god. Then surround it by technological terrors. Tah-dah, you have a non-super laggy army of death that brings you past lvl 100.
