Deviantart membership - worth it?

I'm considering upgrade Deviantart account, but I'm not sure if I need it.
What are your experiences? Is it worth it?
What features do you like the best?
Does it have any influence for increasing popularity of your profile?
I'm very curious so, be so nice and let me know!

EDIT:
I just  receive Month of Premium Membership from spadiekitchenqueen. Now I can check it myself Yay! Thanks a lot Adeline! I hope I can requite it somehow! Please let me know!

But I still waiting for yourin sights!
