I quite like Ryanair even though they nickel and dime you, as long as you go in with your eyes open and fully prepared. It is true, however, that some of their flights go to very secluded secondary airports, so that is definitely a consideration.

Our most recent flight on Ryanair was from London Stansted to Genoa Italy. It was very pleasant and efficient. (cheap too) The seats were comfortable and legroom pretty good. Here is my flight review video.
