Abrams M12A Tusk Tamiya or Dragon +/- Eduard or Voyager??

[Sunny]

To all the Abrams experts out there, i have spent far too long digging myself into an internet hole and would appreciate some advice.   I am looking to build an M12A SEP which as much detail as possible and I have the following options:

 

1) Tamiya M12A with the Eduard PE parts or the Voyager (but they are hard to get)

 

2) Dragon 3536 with the Voyager parts (basic set, the bins, side skirts) 

 

 

Are they any other options worth exploring? I have looked at the E.T Model detail kits but the kit is £100 (over my budget!)   I am particularly interested in the detail around and behind the turret.
