Mostly yes.
There is one specific situation that clearly justifies W11: anyone upgrading to 12th generation Intel will eventually have to upgrade their OS, in order to benefit from the special CPU scheduler included in the latest version of Windows.
As to OP question: I have measured W11 vs W10 using Crystal Disk Mark after my upgrade a few months back to the early Win11 Dev Beta. I have not seen a significant difference, any delta was within the margin of error, and not noticeable when using MSFS. Read performance was a tad higher in W11, Write performance slightly lower,Random IO and latency as comparable as it gets.
