What main hand weapons are better?
Greatsword and Axe/X give the best DPS in PvE.
I prefer axe in most situations, especially in PvE as it still has higher DPS than the other main hand weapons. Personally i prefer axe mace for the vulnerability stacks.
Hammer is so so in PvE, as you don’t really need the CC it provides. Certainly not worth switching out greatsword for it.

Any suggestions?
For raw melee DPS, you’ll want to run Greatsword. PvE foes are teh stupid, and will stand still for 100b, which does tremendous damage.
Axe mainhand does nice damage. The burst is strong. Offhand can be defensive (shield) utility (warhorn) or more offense (axe or mace). For wandering around in PvE I actually love Axe/Warhorn, Axe puts out all the damage you need vs PvE mooks, and Warhorn lets you run around a lot faster with swiftness if you didnt get war sprint trait.
Hammer is more of a PvP weapon. It’s DPS is middle of the road, but its control (stun/knockdown/knockback) is what makes it powerful. In PvE it’s decent but just not the best.
For PvE @ lvl 35 I’m assuming you’re referring to leveling and doing world events. Axe+Shield / Sword+Warhorn should do nicely.
