Arcane
What makes casters so much powerful is when the DM and the player doesn't create characters/settings that makes sense· For eg, on pathfinder a sorcerer of silver draconic bloodline casting sirroco makes ZERO sense. Doesn't matter how cool and powerful the spell is. A scroll of finger of death being easier to obtain than a vorpal weapon makes zero sense. 5e limited far more than 3.5e how much spells after tier 5 arcane casters can cast but also made cantrips at will and greater.
Warlocks are considered the weakest 5e arcane caster because they have a very limited spell selection and their patron can teach (not gave, they aren't clerics) few other spells, so if you have lurker as a patron, you can't learn fireball. At the same way that if you have a fiendhish patron, you can't learn cone of cold. If you force casters roleplay how they obtain magical power and scrolls, much of their power is lost. Just like with multiclassing. It can create pun pun builds and can not.
As for martial classes, i have heard that Barbarians are great on 5e. But never read much about the class.
I personally like fighter companions in games with dumb IA because i need to micromanage they way less.
