Yes, got the Huey as well. Both are great. Not sure which I prefer. Even though I love the real world Huey I think I may lean more towards the MI8 in DCS.
Huey Pros
History
Sound of the Rotors
Side Gunners
More manoeuvrable
More fun to fly around - No Stability controls
English Cockpit
Can aim the Miniguns
More complete atm
Huey Cons
Rather Combat ineffective (maybe I'm just poor)
Not as many load outs
MI8 Pros
Stability Controls
Very large Cockpit
Many more weapon configurations
Wheels - Easier take off and landing
120 rocket barrages!
MI8 Cons
Russian Pit - English mod
Tail haunts me
If you are looking to only get the one I would go with the MI8 as I feel it is more diverse. However there is no campaign yet, unlike the Huey. A small album with some Huey Shots
