Mine is pic related, the Victory Gundam. What I like about it is how modular the mobile suit is. It's the result of years of ms tech late into the Universal Century where now the Gundam is mass produced. In the show the rebel forces are shown to have a stockpile of Gundams in a bunker so they can burn through parts.
Honorable mention to the RX-79 G ground type Gundam from 8th MS Team.

Yeah G Gundam does encroach into some very old timey racist caricatures of other countries through the lens of Japan.
Zebra Gundam is racist as fuck, which sucks because I think the design is genuinely rad. Also, if anybody hasn't seen Gundam Maxter, that's the US gundam from G-Gundam, and it's fucking hilarious. Chibodee Crocket , the pilot of Gundam Maxter, is canonically the shittiest of the main cast of G-Gundam.

He just wants to be loved by his mommies (and Domon)
