What are pros and cons of piezo Vs strain gauges bed leveling sensors?


I'm designing a dual hotend carriage for a HEVO printer that will run in an enclosed heated chamber and I'm evaluating which bed leveling sensor I should use.

I read that BLTouch and similar sensors stop working in a hot environment, and likewise, capacitive and inductive sensors are affected significantly. Piezo and strain gauges (force-sensitive resistors) are my choices.

What are the differences in practice? Both related to the heated chamber (70+ °C) and in general at room temperature.
