Manuela did decent for me in one of my more recent runs where I made her a Trickster with a Levin Sword, a support oriented gambit (forgot which exactly though) and primarily used her as a more supportive unit that could hang out in the frontlines (since stealth made it so she didnt have to worry about taking attacks). Also gave her a few magic stat boosters so she could be a decent combat unit when needed. Also ran a Mortal Savant Dorothea that run as well so I kept them close to each other so they could get an ATK boost from their support with each other.

Hanneman I still havent used, and Im not sure when Ill ever do a run where I do so. But I heard he can be good with a magic bow.

Of course, if youre hang up on using them is other characters can do what theyre best at even better, theres no real way to convince you to try them out in a run. But if youre like me and you like trying out different things each run (hence why I used a MS and Trickster in that run since I never did a run using those classes before), you can make them into solid units if you really want to.
