Hot End Thermal Runaway quite Often. What's the best replacement Thermistor?

The past few prints I have been doing I get thermal runaway on my hot end quite a bit. Whether its while im changing my filament, starting a new print, etc. kind of kills me specially while in the middle of the print since with my ender 3 pro, I have to reset it and cannot just kill power to the hot end and restart it.

From my understanding first steps are replacing the thermistor as its the cheapest and most likely problem to cause this.

What's your best replacement thermistor for best accuracy?

Im running marlin firmware (that could probably also be updated)
