The 1/48 will remain king for me, I have now both Hikaru's VF-1S in both scales and with fast packs. Hands down the 1/48 is my favorite, size & durability!! It just looks so much more aggressive & deadlier! Oddly enough of all my 1/48 Valks, I've never had the wing-flaps or Airbrake come off or get super loose!!
The 1/60 is nice, super poseable, detailed, its big plus of more tampo printing and in scale with my Zero & Mac Plus toys, but thats not an issue for me, Bigger is better!!
And if NB4M were to make anymore 2 seater 1/48's I'll get one from him!!
