Notice all the factors we can't know to help you decide?
Solid state control can allow ~50 to 500 million cycle lifetimes. However you usually need to include a safety contactor run by a second sensor and controller to detect a failed solid state relay (SSR). SSR also dissipate considerable power and require some thoughtful installation work or they fail in minutes.
