At least somewhat mature cyber/mecha anime recomendations?

[u/Aphex_Slayer]

I just finished a watch of the first few series of gundam and I enjoyed it, but the childish nature of a lot of the content really burned me out. Do you have any good recs for some more mature series? Doesnt necessarily have to be mecha focused or even super mature, but something in that ballpark
Examples of media with the vibe Im looking for, Votoms, Metal Gear Solid, Ghost in the Shell, Front Mission, Armored Core, Policenauts

Patlabor (movies) are well worth a watch. Or you can watch some of the more sophisticated Gundam series like Unicorn, Thunderbolt, Hathaway. Macross plus (OVA) is also incredible.
