^ Yeah, but you'd have to do an uppercut stab to do a vertical stab. It's powerful, but it swings too wide and causes you to accidentally hit other parts before hitting the tail

If I remember correctly, lances have a more powerful diagonal stab while gunlances have more powerful forward stab. I know it's circumstantial, but I was thinking lances > gunlances when it comes to general tail cutting.
