What are the best features of premium membership?

I recently upgraded to premium membership on Chess.com. While I know there are many features of premium membership that one can enjoy, I'd like to ask which features have helped you improve at chess the most in the long-term, particularly when you were in my rating range (1600 at rapid, 1400 in blitz).

I don't know that anything has helped me in particular but I do enjoy the site and figure that was worth a few dollars 

everything is there on diamond

i only use the app so i probably to get the maximum benefit but it all depends on how much you work it

they have recently revamped the lessons section and i like it much more than the old version; i also dont know how the other membership levels are affected; with diamond i can do whatever i want

do other memberships have access to drills?- i found those helpful place to practice endgames, really helpful actually; i can do any of those

tactics? i used to do hundreds a day, now i only do a few so this part doesnt affect me as it might someone who wants to hammer a kazillion

i think the analysis features are better?

all the videos; these are always helpful when you need it

i have not regretted my diamond membership but the yearly $ is not an issue atm; if it were i could get by on platinum; maybe even gold

i have not idea what the free version has to deal with as far whatever

i find that when i contact chess.com they always respond promptly and professionally; i am sure the diamond doesnt hurt

membership has its privileges

i am sure there are some min/maxers who can really spell out the differences better than me

good luck

i am sorry; i meant to say on pc it is probably stronger and more benefit than app

If only I had premium... Sad times :.( :mate :resign
