Top left: Neon Genesis Evangelion - most people would recommend it, I'd say watch Ideon and Victory Gundam first idk
Top Middle: Mobile Suit Gundam the Witch from Mercury - decent AU for Gundam, good starting point for the franchise (other than the original show) since it's the big new one
Top Right: Mobile Suit Gundam SEED - it's awful, don't watch unless you really really want to be a Gundam completionist
Bottom Left: Brave Bang Bravern - it's great!
Bottom Middle: Cross Ange - incredibly bad, but it's terrible in a The Room kinda way
Bottom Right: Mobile Suit Gundam Char's Counterattack - fantastic, but it's a sequel movie that has 143 episodes of anime homework to really understand (Mobile Suit Gundam, Mobile Suit Zeta Gundam, and Mobile Suit Gundam ZZ). Amazing, must watch!
Gay rankings IMO: Bravern, CCA, WfM, Eva, Cross Ange (super queerbait on this one), SEED
Bravern is definitely gayer than WfM. I'll admit that Charmuro AMVs may have rotted my brain on that CCA call. Either way, if you liked WfM, you should try Mobile Suit Gundam -> Zeta Gundam -> ZZ -> CCA
Bottom left is Brave Bang Bravern, which is extremely gay. Bottom middle is Cross Ange, which I'm not too familiar with. Top right is I think Mobile Suit Gundam SEED. Bottom right I have no idea.
Bottom right's scene is specifically from the Char's Counterattack movie, but all the core Universal Century Gundam shows have a lot of gay tension in them
