Mechanically, it's pretty cool. Unlike some of the other uglier transformable suits in Zeta like the Asshimar, the Gaza's design is so clean and streamlined. Shoulder shields, decent cannon, respectable MA cruising mode, and easily mass producable. Its later upgrades include a respectable missile armament. The only downsides are that its cosmetically not the prettiest thing in Gundam, and it was constantly plagued with off putting color schemes (like Haman's preference for pink).
