It's not a subscription, but I've bought a couple of the Fellow drops and enjoyed them. Lots of independent roasters that I like also offer subscriptions (in fact, I think almost all of them do) but I tend order from lots of different places.
I was gifted a subscription to Atlas coffee club a few years back. So while I can't comment on value/ price, the coffes that come every month range from good to excellent, and producers used are from all throughout the world. I don't have experience with other clubs to compare, but I'm super happy with this one.
I am quite enjoying the coffee from Fjord roasters in Berlin :)
Every month they have new beans so it also allows for some nice discoveries and some experimentation :)
I've used Trade and Atlas, and I've had a few good coffees from each. They're interesting because they'll send me beans I might not have considered, and it's helped me better develop my opinion on what I do and don't like.
