Well, lets put this way :
1) MSIA ............... MSIA ver. 02 (most of the main suits) ... EMSIA.
2) MG .................. MG ver. 1.5 ........................................ MG ver .02.
3) FIX .................. FIX Chogokin (1/100) ......................... FIX Frame System.
4) HCM-Pro .......... Super HCM-Pro (1/144).
Over the best line I like is EMSIA. I had only one HCM-Pro figure and its the RX-78-2, it was very loose, so I ... and I`m not fan of RX-78 Gundam Ver. ka either. I prefer my Gundams mix of PVC and ABS, I don`t like ABS, only if they are kits.
