[TVI-RFI-EMI] Are nuvistors sturdier than transistors?

[kd4e]

Am I correct to believe that a nuvistor would be more
resilient versus transients from surges such as static,
nearby/indirect lightning strikes, and other emp sources?

Do nuvistors 'age' like tubes or are they pretty much
stable over time like silicon (not germanium) transistors?
