If you're getting all 1:100, I would prefer Nadeleeh because it's the newest Gundam line.
Strike Freedom for 1:100 comes with 3 edition, the basic and limited 1st edition are around 30-40 USD (online price) and not much different from each other. The Full burst eddition, features more movements, can cost you 60+ USD.
From what I heard, the basic edition has a small problem. The wing joints are very fragile and can be busted while assemble.
In the other hand a Virtue/Nadeleeh cost you 25+ USD.
Still working on my tiny Ground Tiren atm =D
