I’d think a well-designed linear power supply would have a reliability edge
over a similarly well-designed switching supply, assuming both had the same
specs, and same parts and build quality, the reason being that the linear
supply is inherently simpler.
The MTBF of each design can be computed, assuming the data sheets from the
components are available, although I’m not persuaded those calculations are
all that believable.

I say with correctly designed linear power supplies, there is a MUCH
lower risk to get an overvoltage at the output than with a properly designed
switching supply.
It seems to me that this is a function of the design and construction of
the regulator, including choice of components, not the method of AC/DC
conversion.
