i'll likely never agree lol, but it's always gonna be highly subjective. again, tho never gonna feel that way cos some things just rub you the wrong way. and it really did then in the 90s when douchebags in oakleys were a thing, a sleazy unctuous annoying thing. maybe they're still a thing--could see especially in contracted private military douche culture, which wouldn't be entirely un-enclave'y. they were intended as assholes, albeit less privatised and more the consolidation of everytihing under the crony capitalists and oligarchs who effectively become the government, shifting to ideals of uniform national identity unity that would quickly take precedence over distinct marketing of brands. it surprises you to think they'd still be catering in any way to what the grunts felt made them look badass--and they were conscripts not people who chose their line of work with youtube videos of yeah them in their oakleys shooting brown people listening to mastadon on their ipod. things fell very fast though iirc in the fallout timeline so it would make sense for the enclave to inherit designs from contractors that still had a dept devoted to making their designs macho, "sexy", and glossy magazine worthy.
but yeah the gas mask above you have looks very serious and utilitarian, like more purpose-built type of ski goggles that don't go too over the edge. it maintains what fallout is to me, imo. i cant really compare the eyes at all, or the segmented lower face of bughelm (from my perspective.) the sample from the animu before it looks v stylised and with merit in its own right for the sake of that. the bug helmet well, looks like a bug, wearing oakleys, the face sectioned off like a mussle but the space its centring on and taking up space and shape almost like its to mimic a hymenopteran insect. ugh. again i'm not young, it looks like how i rememeber shopping for kids who liked bionicle and how all that stuff looked like to me, like some design from somebody's portfolio made it into fallout 2 when it otherwise would not have, but good in its own right (outside of fallout aesthetics, but sadly not its budget and timeframe) to compensate for the fact that again i think at least half of the non-recycled art that made it into fallout 2 was just bad and begged for revision.
and yeah it just being a BUG helmet. and they aren't aliens. well maybe the final boss involves dna from some crash site in addition to whatev piles of fev gene manipulation or idek the lore nvm. and you can loot and wear them--despite no genetic manipulation to place my eyes that far apart like a non-apex predator animal. cars were also focused on having that alien look in the 90s too, sleek swooshy, cars had headlights to look like spaceships or sucked-on candies (and suitably looked awful when they showed wear, no wabi sabi, no "apocalypse awareness"). now angles are involved more but everything still looks like shit. not really topical beyond where our dystopia fork is bleeding into and how interesting our world is.
what i remember in fallout are aesthetics that as far as consumer-geared designs went, they didn't go far beyond jet age. and (urban) architecture otoh looked like the earlier art deco aesthetics decades before lasted forever with maybe multiple revivals (and would maybe incidentally kindof place your second helmet example somewhere fallout'y--NCR ranger idk given the eyes and i don't like picking apart obsidian on how much money/time they had to spend on their art). certain noir comic book styles use a lot of this it seems, like watchmen and batman. brutalism was never really in the game at least as it emerged in the 60s-70s at all, but its common utilitarian ideal of potentially finding cheaper aesthetics in exposed materials and such, and it was around the timeframe that brought us weathered-looking retrofuturism in the first place--much of the gadgetry in fallout had that cumbersome exposed materials look to it with old tech bulging out: half ruggedised, half with mere cages to protect old tech still in use in a dystopia really only still using because they cared even less about energy efficiency and handling waste for even longer than us. they never cared about higher resolution displays because media and art was kept in its place or whatever in a socially conservative world that kept sane through ideals of wholesomeness, unwavering protestant work ethic with an entranced smile, facile doe-eyed bromides recycled amongst amongst nuclear family members common in post-war thinking held through the endless cold war of fallout for forever--a century. i suppose the world of fallout is merely different and maybe we're an accelerated dystopia more obsessed with fossil fuels for cheap energy and will actually meet the precipice of our horrible timeline sooner given global warming--rather than the more nuclear obsessed world of fallout, where overflow of waste, the weapons race, immense genetic testing of fauna not just flora was what left behind the scarred landscape. we'll just have the remnants of proxy wars, before famine takes everyone and the sun's left to bleach everything.
(i feel like i took my concerta twice this morning)
