Haven't played with all of them, but so far: Threaded Cane is really boss and I like the reach on it, the Saw Spear has a really nice feel to it and I like using it but I picked it up late in the game and don't have it upgraded, Tonitrus is really cool.
Very excited to try out the 2 daggers and the Scythe. Btw, are they hard to get or find (no spoilers)?
I feel like people should just wait for the inevitable Complete Edition of the game that will come with all the DLC.
But if you really want it now, I guess it's alright for that price. The game kind of lends itself alright for short burst plays (just take a mission finish it and call it a day), but if you want to get past lvl 20 you will need some more time on your hands and get to grinding.
Like other people said, don't expect an amazing story. You will play mostly because of the universe and the fact that the game looks, sounds and plays really well (imo).
