Well, we've probably done a great job at confusing Cypher226. I really hope not.
Cypher226, I think, overall, when choosing a rule sets, the best thing to do is to to try to define what you want out of said rules. Realism, fun (seems obvious), period feel etc. Also, what Century as that can make a big difference.
For example, Lion Rampant is great deal of fun but really has nothing at all to do with the manner in which we think 'Dark Ages' battles must have been fought (insofar as we can tell). Great game, very loose on the history.
Dux Britanniarum is the almost the opposite, very good on the history, a fun game too.
I suppose, at the end of the day, the best thing to do is read as many independent reviews as possible, though this might not be possible with some of the home grown/small scale print runs rule sets.
