I enjoy Steam.

Zero Ranger

are probably my favorites right now.

Steam definitely has alot of good shmups, but the most I've played was Ether Vapor Remaster, and it is still one of the most gorgeous shmups
I have ever played IMO. I also have both Crimzon Clover World Ignition and Raiden IV Overkill, and both of them are excellent shmups as well.
