I would think that the 15th gen would not have the same issues as 14th but I could understand why people may be abit cautious and I'll keep my 13600K as its been 100% fine and have no real intrest in any other 13/14 gen CPU as a cpu or gpu running 250w is half my power supply budget. Kind of a blessing in disguise now thinking about it.
Best in slot CPU's for some end of life plaform's is kinda a waste of time as I bought a second hand 12600K for £210 while a second hand 9900K upgrade for my z370 was £240-280 and 7700K cpu's remained high for a very long time to the point where other AMD and intel options where better.
