If you look my "Which one is better 1/48 Starfighter Kinetic or Hasegawa..." you can see that I liked the Hasegawa build more than much newer Kinetic..
I don't think this is a fair comparison, the reason is the Hasegawa kit is over 28 years old! If this is to be a fair comparison, compare the Meng F-4 to a Tamiya or Zoukei Mura offering. Hasegawa was the best in its day and still is competitive.
I'm thinking of making Academy vs. Meng comparison, although they have 10 years age difference too.. And I'm waiting for Hasegawa build experience.. Lets see what will happen
