Have the following:
Browning - Defender, Defender pro-scout, Defender ridgeline. The defender (original) is black flash and the scout is low glow, both have worked well. Ridgelines have been garbage reliability wise. Daytime thumbnails are pretty good for all, detection circuits have been good. Browning data plans are the least economical of any i use.
Spypoint - Cell link, link-dark, link-s dark. Cell link is a cheap but shitty solution with functionality and reliability limitations. The link-dark and link-s dark are picture takin machines. Great detection circuit, great battery life, mediocre to average pictures. Spypoint frequently gets a bad rap reliability wise, i think a lot of it is from their cheap link-micro line. The only issue i've seen with the link-dark and link-s dark is there is not a good seal on the battery location and insects and other shit can get in there. I'd put them below some others for reliability still because of this but not as terrible as made out to be by people who've had the link-micros shit the bed.
Ridgetec Lookout - My favorite by far. Good battery life, most configurable options and control BY FAR. Good night images for a no glow cam. You can get low quality video sent to your phone for cheap or all the way up to 1080 video to your phone. Even using video on many of them, my monthly data cost per cam is the cheapest of all my cell cams model. Mediocre daytime pics.
Tacticam reveal SK - This is new so limited time in the field. Detection seems pretty good, thumbnail image quality is very good, cell reception seems great. The app and configuration/control suck. You're very limited in settings and transmittal of images. You get a lot of bang for your buck though i'm still skeptical of long term reliability just based off of reading a bunch on the reveal x.
Spartan - never used but has a good reputation for reliability. Can get cheap unlimited plans by linking to existing cell phone plans. Some reviews historically claim poor detection circuits.
