This is my personal, anecdotal experience:
I ran a 1-20 campaign with a vengeance paladin, beastmaster ranger, arcane trickster rogue, lore bard, and shadow sorcerer. The paladin was easily the DPR king. That player would burn smites like they were going out of style. I tend to run deadly fights with enemies coming in waves. Once the paladin was over 10th level it was difficult to exhaust all his spell slots. The sorcerer also had excellent DPR. The lore bard peaked in Tier 2 and Tier 3. The players of the ranger and rogue had suboptimal builds despite my best efforts to help them.
I am currently running a campaign with an evoker wizard, cavalier fighter, and swashbuckler rogue at 8th level. They're about evenly matched. The fighter is much more effective than I was expecting -- the heroic badass you want a fighter to be. The wizard was the weakest in Tier 1 but now wrecks face. The rogue's player has little interest in direct damage and is more of a lateral thinker who tries off the wall tactics to flip the situation on its head. Good times.
Also running a campaign with an evoker wizard, vengeance paladin, and genie warlock at 8th level. I've house ruled that the paladin only gets one smite per turn. That seems to be having the desired effect. The paladin is formidable but doesn't overshadow the rest of the party. The wizard's player is more fluent in the rules than the warlock's player, and that results in his character having higher DPR.
