Glad you asked here, then all can benefit.
I've only tried Stealth and Moultrie.
Stealth was fine but they didn't have the switching tech and AI filtering at that time, so it was easy to jump to Moultrie. Stealth was sending too many pics, and was disconnecting from network never to reconnect without visiting camera. No disconnects from Moultrie due to cell, only dead batteries or a complete camera malfunction (1 I think in 3 years, possibly 2). Moultrie has a few day where it doesn't connect, but everytime it's reconnected eventually without me having to visit the cam.
So if Stealth has caught up in tech, I can't compare because I haven't used it with these features.
Very happy with Moultrie, so much so, all the cameras I've bought his year have been out of pocket at retail at Cabelas/Sportsmans (Brock and Ryan got the comp'd cameras). I'm running several year-round over 100 miles from me. One camera has been on same tree for 1.5 years with only one visit to freshen batteries, which weren't dead yet (Edge 2 Pro)
My plan is comp'd and using the unlimited $16/month/cam with the 8-10 cams I'm running. You might get it cheaper by bundling but since mine's comp'd, they don't do it that way. But if not, when I'm in full season, I'd be spending up to $160/month on plans. Way less than I'd be spending on mileage if I were visiting the cams.
Even if they didn't comp my plan, I'm staying with Moultrie now that I know their system and have received thousands of images successfully over 3+years from 4,000 to 10,000 ft elevation and below zero to +100 degree temps, with little fuss.
