I've previously owned both the Maverick ET-732 and the iGrill2 (pre-Weber buyout) and liked them both. The Maverick was solid but was prone to limited range from my patio area inside to the bedroom. The iGrill wasn't too shabby, but the probes back then were stupidly expensive and I did suffer a few drops.
If you're not married to Bluetooth or RF, I think that a WiFi enabled therm is the way to go. The Meater is both bluetooth and WiFi (though I haven't owned one), as is the new iGrill3. If you're looking for a "Cadillac" model, I think the Fireboard, Tappacue, and Thermoworks Smoke (if you buy the WiFi Gateway) all are rugged and have great extended functionality (including graphing your cooks).
I purchased the base Fireboard package, along with a couple of extra probes and and completely satisfied with it. I've found it to be dead solid accurate when I calibrated it and it provides enough data points to drown my BBQ geek nature.
