Frostreaver vs Reaver - leveling weapon

[baue1446]

So my lvl 9 pally has a few weapon choices trying to get the most dmg output i can. I'll likely solo with fungi all pre 50 so making sure I do the most dmg possible is what I'm looking for. So frostreaver is 42/43 with 50 hp +stats and a proc that doesn't go off till 50 so not a factor. The reaver is 40/40 no hp just resists.

Which is better? Any other weapons out there a 9 can pickup (besides primal) that I could get thats better?

I also have Hammer of battle 1hb from statue (17/25)
