Hi, Lieutenant,
I think each game has its pros and cons. Like Dale says, if you like small battles and the trans-Mississsippi, Ozark is a good game. If you like a lot of musket-armed units, Shiloh, Peninsula and Bull Run provide them, as well as Ozark. If you want large battles, you already have two good ones, but Atlanta, Antietam or Chancellorsville would fill the bill. Peninsula has a lot of large units. Most games have a lot of scenarios. I think there is a thread where folks listed their favorite games. I will try to find it.
And here it is!
