However, there are plenty of amazing 3* and 4* units. A few to look out for are
4* Armin who is a beast of a tank. Carries me in a lot of late game content.
3* Elson with his insane buffs.
3* Tieria who I personally think is the best character I have. She's totally broken with her combat readiness skill.
3* Bask who's really good for a free unit.
and a bunch of others like Clarissa, Angela, Achates, Karin, Silk, Cidd, Carmainrose, Kiris, Jecht, and Kluri.
All of these units are usable and a decent amount are better than 5*s
This is all from my personal experience both playing with these units and dealing with them in PVP as well.
