It is definitely worth trying out, I'd say. Sure it has its faults but I find it to be very entertaining, and has engaging content.
If you're used to OSRS combat, I'd look into "Revolution" -- this essentially fires off abilities automagically, so you won't have to manually use abilities.
There is also Legacy combat mode where it works just like olde runescape for the most part, but it's fairly inefficient damage for bossing, for example.
Skilling is much quicker than OSRS, and there's a lot more methods/areas to train. It's good fun though, I really enjoy the skilling.
Some skills have been reworked (Smith/Mining pretty drastically from OSRS).
