>>7542644You just got the one that's the best in terms of articulation, scale, and general aesthetics..
Sticking with affordable Classics/Generations stuff:
You've got your OG Classics 2006 Deluxe Starscream, good transformation, good altmode, and pretty much every seeker is available in that mold if you want them to be uniform, but a bit on the chonky side, the guns are too large, and the articulation is a bit shit, and he's a tad small. There are a couple of decos, the original Classics is a bit overdone with the markings, the Universe repaint looks more like the cartoon but is riddled with QC issues, the Henkei version is good if you like chrome, but overall the best release is probably the United 3-pack with Thundercracker and Skywarp.
The Fall of Cybertron wave of Generations brought their take on Starscream, and while the game is technically part of the Aligned/Prime continuity, the design is pretty much just the G1 design with an alien plane mode and gatling guns. The FoC wave is pretty notorious for being shit, but the Seeker mold is probably the best toy to come out of it. Great articulation, double-jointed elbows, wrist swivels, ankle-tilts, etcetera. Transformation works great, with no fake parts. Undersized, but not bad. Skywarp and Thundercracker also exist, and the Japanese version of Skywarp has a predominantly purple scheme so works decently as a very expensive army builder for the purple Air Warriors from Season 1.
Thrilling 30 brought a Legends Class Starscream based very loosely on his design from the Furmanation era of IDW, with the F-22 mode. It's basically a downsized version of the Classics toy, with a different alt mode and a more toon-accurate transformation for the cockpit folding into the chest. Articulation and proportions are slightly better, too. Skywarp, Thundercracker, and Acid Storm exist, and Starscream and Acid Storm both come with a tiny bug micromaster/targetmaster partner that in Starscream's case is Waspinator.
