i like the original gundam designs because the show reminded me of ww2 movie cinematography and design aesthetics, and also the Iron-Blooded-Orphan robots are cool even if the show glamorizes a pretty gross mafia harem owner. 30 minute missions are also cool, but i prefer larger scales than 1/100 or 1/144, but those can be expensive compared to gunpla. most of my gunpla/30MM models have been under 20 american biosurvival tickets while maschinen krieger models at 1/20 scale are usually around 40 or 50 for power armor. Dorvack is neat because the show ~~sucked~~ was unpopular so the models are mostly not very valuable and you can find them on ebay for like 30 american biosurvival tickets sometimes. plus they are 1/24 scale which is the same for a lot of model cars and tanks and planes and also the same scale as the Hexa Gear series of models.

at least model kits give you something to build and sometimes articulate/pose unlike funko pops lol, even the SD (super-deformed, chibi proportions) series of gundam models retain a hint of the original art style unlike funko which digests every IP into an indistinguishable bolus of media slop.
