I too have had MDR's fail on. An SCR too, but that was on finicky control system.

SCR is probably going to give you the longest element life, but may be harder to source, and probably more expensive as you up the amps.

SSR is probably going to be the cheapest option of those offered.

Personally I'm still on mechanical, the metronome click lets me know it's working without looking at it, and I can usually hear when it's on it's way out. I've also got 24 of them laying around, so it's the free option.
