It doesn't help that the both of them put unconditional trust in Cu (because Lancer is their first Servant, retains his Caster-self's memories from Fuyuki (and he saved them then), and is hugely reliable) and that Kana is a constant reminder of his past misguided beliefs.EMIYA's saltiness is probably a direct result of the stress he's feeling from the Masters being his parallel self's children (something not canon to standard FGO, and might increase his stress level and emotional baggage).
Not to mention everyone rags on Archer automatically so he's always just a bit salty there, especially since Gilgamesh is around; even though he and EMIYA have an uneasy truce (because Gilgamesh finds the twins amusing and Archer doesn't want to destroy Chaldea in the aftermath of his maybe-murder-suicide) Archer still very much dislikes Gilgamesh and the feeling is mutual. They just get catty instead of killy.
And despite having no children and still disliking Shirou (they may have reconciled but they still annoy each other, even though EMIYA's slaved to Alaya forever and Shirou is currently dead), he still feels obligated to look out for 'his' children - which he does willingly and unquestionably because they're also Rin and Arturia's wards, but it still bothers him. And because they're 1) technically his children, 2) Rin's children, 3) Arturia's godchildren, 4) his Masters, 5) appreciative of his efforts, and 6) responsible for this respite from an eternity of slaughter as Alaya's dog, he cannot and does not want to ever snap at them, despite them being idiots on (many) occasion(s).
Honestly being Archer is still suffering. He's only ever comfortable in the kitchen, because cooking and cleaning are both activities that help him relax, it's something he's genuinely good at and people actually like his food, and seeing happy people still makes him happy. Especially Mashu; he doesn't feel like he has the right to judge Ritsuka's potential girlfriends, nor does he think he has any authority on whether or not Ritsuka keeps a girlfriend, but he approves of her on just about every level.
It's a shame she's going to die young. And he knows it.
