+4 to main stat?! You know that the standard array at level 1 stops at 15? You can't have more than +3. A Monk with the Standard array, assuming a +DEX/+WIS race can have 16 in both WIS and DEX (for an AC of 16) and then +1 to CON. A heavy armoured Fighter can have AC 16, +3 to STR and +3 to CON.
Did you just ignore the parenthetical where I said "because I've done that math already"?
Because, you know what you just did by changing all those numbers to 16's? Reduced everything by the same amount. All of that damage I did at +4 got reduced by the exact same amount.
I also admitted that the Fighter likely has a better con. HP was never once a consideration for me. Yes, Figher has better Hp. Not contesting that. It was the other aspects I was contesting.
So, your objection ignored everything else I did, and made no impact on my analysis... congrats?
First, I do not think 50% of your battles are half your level in CR (in my experience your average combat is around your challenge rating), and I don't think you'd be wasting your stuns on those half-level CR battles either. Do you? I mean let's be realistic here, you only get your level in Ki points per short rests and you're not wasting them on the Orc, you're holding them for the battles which count (particularly if many fail), so let's be realistic here and assume it's foes closer to your level in CR and higher that you'd even want to use a stun on.
Here are your average Con scores for Monster Manual creatures by CR for levels 4 to 12. I think you will find, for the realistic situations where you'd even want to try to stun, that it's going to come out to less than 50% chance of working.

The big problem I have with this concept of "average con score" is that it assumes that either A) Monk players are stupid or B) Everything is close to the average.
A stupid, easy example.
The Monk player has two creatures they can attack. The Archmage (CR 12) or the Heavily Armored and Otherworldy general of the Hells, the Eryines (CR 12).
Which one do they stun? Without even knowing there stats, you pick the Archmage. They are more likely to fail the save (+1 Con save) while the Eriynes is likely to succeed (+8 Con save)
Looking at the average is assuming the Monk doesn't try and pick their targets intelligently, and if they do, then it matters a lot more
which monster they are fighting than what the average score is.
So you're saying their ability is useless against brutes, which make up a large portion of most published adventures and most published monsters?
OK. This is not persuading me monks don't suck though. You've reduced their utility even more.
Your argument appears to be along the lines of "Poison damage is awesome because you'd only use it against creatures not immune or resistant to it so we should only judge it based on what it can harm the most." It's kinda a silly position there Doc. If you reduce the utility of something drastically by saying it's only used in even more limited situations, that decrease in utility should be part of the analysis and not "a benefit".
sigh
But making the argument that poison is a waste of time and a worthless damage type because everything is immune to it is also false. There are creatures that are not immune to poison, and we can't forget that.
Yes, Stunning Strike isn't as useful against a massive brute. But, every class that does saves has pretty close to the monk's numbers, and some of the
most dangerous enemies aren't brutes.
Meaning the enemies the monk can stun reliably, are more dangerous, and even against brutes, they have about a 50/50 shot. Which is not terrible for something that is a rider on their normal actions and bonus actions.
