Reliability 7.3 vs 6.2

I have lost two 7.3s and a 6.2 in the last six months. One 2022 7.3 with 62,000 miles that dropped a lifter and required a long block. One with 144,000 miles that lost a lifter bearing. Was able to replace that before it took out the entire engine as well. Didn't find all the ball bearings though so while it runs smooth now, I feel like it's a ticking time bomb. The 6.2 broke a valve spring and dropped the valve taking out the entire engine at 156,000. Can't find a 6.2 engine currently unless it's from a junk yard. Had many great 6.2s though. Time will tell, but not crazy about the 7.3 at the moment.
I personally drive a 6.7. Just traded my 2019 with 244,000 miles that required nothing but normal maintenance. Hope I'm as lucky with my 24, but I don't trust anything built post covid as much.

The one you fixed, it got a new cam and lifters?
No 6.2 remans available? if there was. Are they or were they cheaper than getting a 7.3 motor?
What do these trucks do?
Full loaded in the bed or are they puthing all the time?
What years are these trucks?
How are the transmissions doing?
I wonder if ford is quietly adjusting the oil pump up at idle on failed 20-22 7.3s. like the recall on the 23s.
Or was it lowered on the 23s and they realized it was a bad idea.

I noticed a while back that random times, my 22 7.3 at idle when transmission is in neutral after a few minutes makes a slight rattle, not a tick per se, and it goes away with a tiniest amount of throttle input. I thought it was a loose tensioner at one point but it only happens at idle with foot off the gas pedal and I can't find anything loose.
I don't use my truck for towing as much these days, with my primary work picking up and demanding more of my time, I am probably going to be out of my SD in the next year or two with the expense and hassle of doing business becoming a bit much, maybe Ford will get their story straight by then, if I still have mine. With all the influx of labor to the southwest last few years more and more labor is on the market and a lot of them are using bogus accounts for hauling work without following any of the regs, I can't compete with their practices.

I was excited for the 7.3 and the return to pushrod design, for the simplicity and reliability. It is unreal that ford managed to jack that up, I guess they forgot how to build pushrod engines. I'm sure they'll get it ironed out, but man is it unfortunate that yet another engine will have questionable years to stay away from. Also, there have been engines in the past from all sorts of builders that got a bad initial reputation from bad "batches" for one reason or another, then after 10 years or so the bad ones were basically all gone and what remained was safe to buy. Hopefully the 7.3 is that.

You feel both 7.3 failures weren't the same?

No remans available anywhere for the 6.2 I can find. Haven't had the best luck with Jasper so hope to get a Ford reman.
The 6.2 is a 2017 and was worked the least. Very lighty loaded mechanic truck, with all highway miles. One 7.3 is a 21 and the other a 22. They are both field supervisor trucks that have a mix of highway and towing miles, as well as fairly high idle hours on job sites. I suspect the idling is what got both. Unfortunate though as it is a required use of these trucks. Transmission have been good in all of them. The 21 was never the smoothest, but didn't have any problems either.

Correct... but the V10 referenced in this thread was a 3 valve head and that required a new spark plug design because of the small bores on the modular engines. Those initial plugs were a two piece design that caused problems when removing them.
