What is your favorite borderlands?

Feel free to say why.

Technically, I think it's BL3 or presequel.

As for gameplay, it's BL1, by far. Reason is my favorite character of all of them (haven't played BL4 yet) is Lilith. Nothing like affecting bandits with an elemental effect, disapear, and repeat. Also because of her speed when using her action skill. Mordecai pistol or sniper were my close second favorite builts.
