>>8883783I've built three so far : G1 Optimus, BumbleBee, and Drift. G1 Optimus is the best one IMO as far as build experience, and posing. There are some parts where glue is recommended like those light blue plastic pieces that make up the windshield. The picture is my G1 kit unpainted, no panel lining.
Drift is an OK kit but don't bother unless you're gonna panel line it at the very least. Out-of-box it looks awful.
Bumblebee looks good but is an absolute shit-tier build experience. Look up reviews and you'll find people cursing a few steps that are infuriating to execute with human hands. Mainly, for me, the waist to abdomen connection, and the god-awful connection of the chest-plate.
I'm looking forward to trying their Arcee and Windblade.
