I don’t have any of the three mentioned here. But I’ve heard great things about the Fireboard, both here and on another site where many members have them.
The Meater, like you say, has had issues. Both with working and then delivering product - although that may have been just on the Meater Block.
Wish I could help more, but I do know when I order another thermo, it will be a Fireboard.
Currently I am using a Chef Alarm by Thermoworks. I like it, simple and fairly inexpensive. I use multiple probes and just plug and unplug to check multiple temps. Not wireless to an app, but I don’t necessarily need that.
Hope you find the info you need.
