Thule EasyFold XT2 is a popular option, when available. I went with the Motow carrier and option lift. My requirements were for 2 bikes with very different wheel sizes and wheelbases as well as easily changing between a 1 1/4" hitch receiver and a 2" receiver.
If you just have a single bike and a 2" receiver then I would strongly suggest looking at motorcycle carriers. They can carry 400-600lb easily, tie-down options and are much cheaper than either of the first two options.
Swagman and others have good options too, but you need workarounds for the fenders etc. but there are ways around that.
