I tend to play WotR with polaxed (from the Lance and Longbow society) as it has a great period feel and battles play out as you'd imagine from reading the sources. However, while I like my wargames to be as close to a simulation as possible I know that I'm in the minority! Polaxed can be rather formulaic, with less nail-biting moments where success hinges on an important dice role than other games, so if that's what you like it's not the game for you.
If I'm strapped for time or fancy something more casual Lion Rampant plays nicely, and though it's rather more Hollywood than historical it's certainly good fun. It depends what you're after, but Lion Rampant fits your request quite well - maybe with some of the modifications published in wargames illustrated for added flavour?
