pure HC vs pure HA, the HA definitely wins the better class award. HC just have more options to hybridize. For instance my HC (ballsy) has this build:
Level 30 (4 420 577 xp)
* Strength: 18
* Agility: 18
* Hit points: 59
* Converted: 2
* Ironflesh: 3
* Power Strike: 6
* Shield: 0
* Athletics: 5
* Riding: 6
* Horse Archery: 3
* Power Draw: 0
* Power Throw: 0
* Weapon Master: 6
* One Handed: 1
* Two Handed: 118
* Polearm: 50
* Archery: 1
* Crossbow: 110
* Throwing: 1
Perfect for harrasing enemies in close combat and still effective on foot and even in duels. I am kinda regretting the 50 polearm though. Not because it isn't usefull, or because I'm lacking in other wpf (120 melee wpf is more than enough for me), but simply because I rarely use lances, prefering to just use my bastard or longsword. It does mean I'm not that effective against real cav, but a lot of cav fall for a simple ctrl-J trick, allowing you to slash them a bit, followed up by a shot to take out their horse. Once they're dishorsed, just close in, block their stab and bump slash 'em to death.
