As I have mentioned in other threads several times as have others is that 1/48 is a great scale for doing in scale dioramas as there are thousands of model kits, accessories and so forth in that scale especially when you consider O scale train stuffs. Just look at military modeling kits with soldiers, support crew, pilots, accessories, air field equipment, jets, choppers, tanks, everything available in 1/48. Then add on all the O scale train hobby stuff and it is quite vast.
Also, I love the new v.2 1/60 but those skinny legs and high heel feet just kill me. The 1/48 has much more robust "calf sections" on the legs and better looking feet. The 1/48 looks burly and menacing. The 1/60 is a little bit cute, which is nice. Which reminds that if they do come out with a black stealth 1/60 I will get it and put pink hellow kitty decals on it. (not joking).
