From my own casual investigations, Wheelock is considered a perfectly good textbook (particularly for people with lots of experience learning languages, e.g. grad students in the humanities), but also a bit "traditional," focusing more on learning grammatical rules and less on developing an intuition for the language. Lingua Latina Per Se Illustrata is at the other, "immersion"-oriented end of the spectrum.

My latin teacher used both wheelock and lingua latina. They complement each other really well.
