IMO-
Some of the best Deku ships are ones that keep both charicters in check so that they don't turn out into what they both fear to be-
TodoDeku: Izuku and Shoto would definarely check in on eachother and be fully honest with one another, it's a basis in their relationship. Izuku makes sure Shoto dosent become like his father and is able to help reign him in if those tendencies slip out, while Shoto would make sure Izuku dosent work himself to death lime All Might
ShinDeku: Izuku does everything in his power to affirm that Shinsou isn't a villain and he is an amazing hero(he has receipts). Shinsou just- Mind controls izuku into sleep so that he can cuddle him and their cats so he could also get some
NeiDeku: Izuku keeps Neitos ego in check and helps him calm down a bit and relax, letting him be himself and not get lost in rivalries and competition. Neito shows Izuku that he isn't what he has been told for years, he isn't useless, he isn't stupid.
KamiDeku; Izuku would help remind Denki that he is smart in his own ways, that he is usefull, he may burn out, but they can rest and recharge. Denki makes sure Izuku feels loved and special, he makes sure Izuku dosent burn out himself.
