Ok yes, I hear you, I feel you, I get it. Buuut..
I've been a spear main for most of my 500 hours into this game so let me try to sell you on some of the advantages of using a spear.

It mainly comes down to attack speed. Slower than knives, but noticeably faster than swords or maces; it hits a sort of sweet spot in terms of it's damage output that favors a very defensive and technical playstyle. It's especially good when paired with a buckler. Bucklers have a much higher crit bonus than other shields but also lower block armor and block force. The spear's attack speed allows you to take full advantage of the slightly smaller counter-window from bucklers and you can also cancel out of spear attacks quickly if you need to parry again or roll under an attack.

But the hit box can be frustrating while you're getting used to it. It can hit things that are at a higher elevation which can be nice in the mountains, but not being able to hit things lower than you can be frustrating in the meadows or black forest. If you have to attack below you, use the throw (middle mouse button). It takes some practice, but at point blank range the spear will go directly back into your hand making it more like a long thrust. If you can just move below them though it's often more practical.

The other main drawback of the spear is with it's damage type. There are some tough enemies that are weak to it like Trolls and Lox, but also several that are resistant to it like oozes, skellies, and creature spawners. For this reason you might want to carry a blunt weapon as backup for these encounters. I like using the two-handed hammers as they're also useful in dungeons for attacking around corners.

TL; DR
Spears have a high skill floor and cieling, but can be uniquely rewarding. When mastered, spear mains can have the highest damage output in your party.
