Honestly, it's up to you. Most of the polearms in the game are very well balanced as far as what they are and what they do. I have a soft spot for the Great Long Bardiche and it's ability to pretty much 1h anything that's not in plate. I don't really feint much anyway
Also, Pikes, Longspears, Awlpikes. All of those are great if you want to play more of a support-orientated 24-15 build. I can 1h people with 8ps while using a Pike, and if I don't get the kill, somebody else will, due to the insane amount of polestun the weapon gives.
