I'm quite happy with the Bosch Smart Home Thermostat II. It has no bells and whistles in terms of AI or other bullshit but works really well with the integration.
Pros: works really well
Cons: no AI bells, whistles

I used one of the MotoRad safety thermostat's that have a 1/16" hole already in them, in my 84. So.. No, I don't think you'll have any problems adding a hole.
Pros: pre-drilled hole, no problems
Vehicle:
Jeep
It’s the thermostat 99.9% in this senecio. They are on back order from Jeep and the aftermarket ones are horrible.
Cons: aftermarket ones horrible
The replacement thermostat came from BMW. No problems this time.
Pros: no problems
Vehicle:
BMW
Just make sure you buy a genuine Nissan thermostat. I don't know what it is about these cars, but they do NOT like aftermarket thermostats. Just spend the extra ten bucks on a Nissan part.
Pros: genuine part recommended
Cons: aftermarket not liked
Vehicle:
Nissan

The Mahle thermostat arrived today along with all the other bits I think I need to put the car back together. The problem is that the new one doesn't quite match the old one.
Cons: new one doesn't match

Cons: did not fix issue

I had the same problem when I put in the all aluminum graf waterpump. It had a bad thermostat right from the factory, I replaced the thermostat after trying all sorts of coolant bleeding, temp logging, etc. The oem thermostat solved the problem.
Pros: oem thermostat solved problem
Cons: bad thermostat from factory
I literally had my cummins thermostat fail and overheat like 6 months ago on a long trip. Popped the housing off. Pulled the core. And drove home without issue.
Cons: failed, overheated
