I went with Removaly after comparing them with a few other similar services. What really sealed the deal is how communicative they are. I noticed them on Reddit talking about their service in a very no pressure way and they seemed helpful even then.
Once I signed up, they were even more about communication and constantly give me updates to my information. If you reply to any email or send one yourself, you get a response back in very short order. These guys are so helpful and personable, I love that.
