>Are the legacy CPU's really better for this use-case?

Yes. Legacy CPU's have the advantage of years and years of testing. Newer CPU's are not as reliable for safety-critical systems inasmuch as not all the kinks have been worked out, and there may be catastrophic bugs in newer designs that won't be discovered until mass deployment on consumer markets.

Meltdown and Spectre have sent shock-waves through the safety-computing industry. I wouldn't want to fly on any plane that is running on the latest-generation Intel chips - they're just not settled yet.
