I'm doing stupid nonsense.
Specifically, since the two SRDs are both CC-BY, I'm combining them into a single document/system for free rerelease.

For most of things I can just combine them, many things removed from 5eR were SOVLful RP/flavor ribbons like Favored Terrain or Tongue of the Sun and Moon, but I need advice on one specific feature.

>5e0 has Paladin able to smite on literally every attack, plus spell smites. This is 3 times per round, 4 if they provoke, even before common multiclass nonsense which can let you hit 6 or more.
>5eR has Paladin able to smite only once per turn, on their turn, as a bonus action.
Both of those have been pretty contentious, so what is an actually reasonable amount of smites per round?

I have an idea banging around in my head, but I want to hear everybody's uninfluenced takes before I put in my own two cents.
