I have at least 1 of every feeder mentioned in this thread.
My absolute favorite is a 600lb Aluminum Outfitters feeder. It is all welded aluminum construction, all wiring shielded, hinged lid, uses "The Timer," on skids, very nicely designed and constructed, and easy to move because it's lightweight. I have 1 of these. Highly recommended but a bit expensive.
My second favorite is the GreenGo 800 lb. All the same attributes of the Aluminum Outfitters also apply to it, except it's all steel and heavier. I like that the timer box is welded in the corner of the hopper just under the lid and the wiring is shielded inside steel tubing. It's extremely sturdy, built to last forever, all welded construction. Only the motor and spinner is inside the varmint guard below, so you really never need to open the bottom access door unless you have a motor problem. It is also a very good value for the quality you get. Reasonably priced. I have 5 of these.
I have 4 of the All Seasons 1000 lb feeders. All Seasons feeders are ok, but the GreenGo is a much better designed and constructed feeder for several reasons. The ASF is thinner walled, riveted construction vs all welded for the others. The ASF doesn't protect against varmints as well as the others. It tends to eventually leak a little around the rivets that hold the spring clips that clamps the lid. My biggest gripe about the ASF is that it has a completely removable lid with a very short skirt around it, held on by very flimsy spring loaded clips. My lease is in west TX where there's frequent high winds. On multiple occasions the wind caught the lids and ripped them off the feeder because those little spring loaded clips don't do a very good job of keeping the lid secured. Consequently, we supplement the spring clips with ratchet straps over the top to keep the dang lid on them. I will no longer buy a feeder that doesn't have a hinged lid, with the hinge welded in place.
I have 4 Lamcos. They are ok too, better than the ASFs IMO. They still have removable lids like the ASF, but they use better lid latches and have a better varmint guard system, being 2 narrow disks surrounding the spinner. I like the way their timer box is designed and in a better location on the side vs the bottom. However the timer boxes are a bit small, so on mine, I don't have enough room for the full size 12v gel cell batteries; I have to use the more compact size square batts which aren't as commonly found as the larger rectangular batts.
I have some Ranch King feeders, and they are nice in almost every respect, but they are super expensive and don't do any better job than a GreenGo that is every bit as durable.
I've tried virtually all of the better known brands of feeders, but I've pretty much settled on GreenGo for quality:value, even though I do like the Aluminum Outfitter slightly better. The AO is just more expensive.
I even have a Cannon feeder. It's an interesting concept, but it's very unreliable because it draws high amps to run an air compressor used to "fire" the corn, unnecessarily complex, drains the battery quickly, makes a lot of noise, is extremely heavy and difficult to move, I can't keep mine running for very long.
