Which server sounds more fun?

[Kuza]

Which server sounds more fun? Based on your knowledge and experience with other servers and hype, pick the server concept you think would be the most fun overall.

RP Playerworld - Your average roleplaying playerworld. You level up, gain stats, magic/skills/weapons/items and then there's the character creation process. There's an economy and everything is based on RPing.

PK Playerworld - You collect fullhearts, weapons and systems through quests. There's not much roleplaying, unless you give each quest an interesting storyline, same goes for the world. Your main objective here is to spar/PK people. No economy, but events and mini-games for when you're not in the PKing mood.

RP/PK Playerworld - The best of both worlds. It would be somewhat unbalanced though.
