I'm sure you'll get different responses from different people, but in my opinion Man/Elf, Knights, and Dwarves are the strongest Free Peoples (and Elves if you don't ban
Galadriel LR). In my opinion Southron Archery, Morgul Orc Swarm (with nazgul), and Corsairs are the strongest Shadows.
Here's one of my favorite decks:

You want to be playing on your sites and you can always triple 3-6 or 6-9 (or even 4-7 if you get your site 6) once you are set up.
The Free Peoples can handle just about everything once it's set up, unless you face a deck that can play
Saruman's Power multiple times. (If you play against a deck that does play
Saruman's Power you play your forts carefully and hold onto one or two
Sixth Level to set up again once they play it, but it's rough).
Fourth Level + Citadel kills anything.
Fourth Level +
Stone Tower kills anything.
Fourth Level +
Gondor Bow is really good too.
Fifth Level is beastly once you get most of your fortifications on the table. The Banners let you heal the wounds you get from using 6th level, and you can also pitch them against site control decks if necessary. This deck also just rolls Corsairs and I really hate Corsairs. Wounding decks (like the shadow this is paired with) can be difficult too, you just need to play careful, kill companions and replace them with fresh ones at opportune times, and try for a shadow kill.
The Shadow can kill just about anything.
Desert Lord +
Seasoned Leader will do 3 wounds and not much can kill it. You use you exert to wound guys to exhaust out their companions, then use
Haradrim Marksman plus a few other guys to get kills. Morgul Ambushers are fun too since you add so many threats.
