WICKED JELLE! I tried it once and immediately knew I would never stray again. It's water-based so it's compatible with all my toys, and easy to wash off. It's THICK, which is not something I'm used to with water-based lubes and is required (for me at least) for any sort of anal play. And it stays exactly where you put it. I've tried a handful of different lubes and every single one dripped right off the toy or needed frequent re-applying. Wicked Jelle is my absolute favorite, no contest.
