12.5 DPR (Greataxe) plus potential Cleave
spell slots: 2 warlock short rest spells, 2 Paladin slots
Vengeance Paladin 3
[Hunters mark = Hex.] Strength Stat is 17 (same attacking stats).
You have a few extra 1st level slots per short rest (but I have a free Divine Smite slot, and an extra 1st level spell slot, so that's a wash). I have a Fighting style and better Lay on Hands.
Vengeance paladin is also attacking at Advantage (unlike the Warlock), with zero action economy drastically increasing DPR.
The 'Lock could also (Darkness + Devils sight) for advantage, but that's an entire round to set up, and it screws with other party members, and you cant be concentrating on Hex at the same time (dropping DPR)
Advantage mono-Paladin.

12.5 DPR (Greataxe) plus potential Cleave
spell slots: 2 warlock short rest spells, 2 Paladin slots +1 Divine Smite
You gained a free divine smite, and advantage to hit (oath of enmity).
The mono Paladin already has the above, and now just also gained GWM (+3 to damage, bonus action cleave attack) and his Str is now 18 (for an extra +1 to hit, and damage).
Advantage mono-Paladin.
Yes close.

18 DPR (Greataxe) + potential Cleave + potential Hex
spell slots: 2 warlock short rest spells, 3 Paladin spell slots +1 Divine Smite +Hex + Misty Step
It's not even close at 5th.
Mono Paladin now has 2nd level slots (and spells), a supercharged familiar (find steed) such a Large Celestial Dire Wolf following it around everywhere (with 25 HP of its own, AC 12, and a Slam attack for 1d8+2), and extra attack (
doubling its DPR).
Spams Hunters Mark then attacks twice (at advantage, and +7) dealing 3d6+7 damage, plus an angelic Wolf attack dealing 1d8+2 (or healing someone).
The Warlock 1/ Paladin 4 can only look on and cry.
