In seriousness: great quests, great music, you can take a break for months and never have to worry about the game changing massively and your progress feeling worthless, fun boss fights at the high end, and technical pvp for those that enjoy it.
Im assuming OP meant OSRS with "original RuneScape" because rs classic is dead, and rs3 is a mess even though it has its ups sometimes.
