So what my post actually does is update Gladius Legis' math to include the extra damage from criticals in the calculation of the Paladin's damage.

So to answer your original question with more accurate math, the difference in damage is +1.925 for the paladin assuming they used 1 3rd level slot versus the wizards 1 5th level slot.
The effects of different spells add together while the durations of those spells overlap. The effects of the same spell cast multiple times don’t combine, however. Instead, the most potent effect—such as the highest bonus—from those castings applies while their durations overlap.
So getting back to the example: +8.2 dmg for the fighter due to low enemy ac.
Your turn 1 netted you: 8.2-9.75 = -1.55 dmg
turn 2: -1.55+8.2 = +6.65 dmg
turn 3: 6.65+8.2 = 14.85 dmg
turn 4: 14.85+8.2 = 23.05 dmg
Fireball does
Turn 1: 24.4 (using your number without double checking) -> 24.4-9.75 = +14.65
You catch up on turn 3 in this fight. Could be turn 4 against higher AC. Fight's are typically over in 3-4 turns. Against low ac enemies haste was slightly better. Against moderate to heavier AC enemies fireball is likely better. But not by a lot in either case.
1. Extra damage from crits is not straightforward as do you smite on the first attack if no crit or wait till the 2nd attack to see if you crit. Your decision point there matters and I never seen it stated.

Speaking personally, I always used it on the first attack, since there was no guarantee of hitting, let alone critting with the second.
This is a good point...IME, paladins crit-fish a lot more when they have advantage.
