Think Altar of Freedom was the first video I saw of your guys'. It looked solid and I remember reading over the ruleset. I'd be happy to see it revisited, the ACW is easily my favorite period to game. Blucher remains my favorite game system I've played for miniatures, though certainly rusty now. Teugen-Hausen (please be spelled correctly) was some time ago and was the only time my schedule lined up with a Blucher game night.
I always have fun playing C&C Napoleonics, although it abstracts just a smidge past what I prefer. There's something really nice and immersion-building about seeing the names of all the actual units (brigades/regiments) in games, and I think my primary gripe with C&C is that missing bit. Even so, the Grand Battle format is great multiplayer fun, and as a game in itself it's solid.
Then again I am a bit of a noob when it comes to minis, I tend to be a hex and counter wargamer. Funny I joined this group hoping to play Black Powder after I bought the rulebook, then found AoF and Blucher, both of which I immediately liked more.
That being said, I will always enjoy and be perfectly happy playing Altar of Freedom, Blucher, C&C Napoleonics, or Horse & Musket. It's been cool seeing so many different systems. I've always had fun playing with you guys, just wanted to throw my two cents out there.
