They are far from a back stab, here's why...
I have dissected them and there is a lot more clamping area on the Wago vs a back stab connection
The Wago spring clamp is a lot stronger than a back stab
On a back stab, (mostly on receptacles) the wire is subject to move every time something gets plugged in & unplugged, after a while this will loosen the connection and it will either pull out or heat up from high resistance.
With a Wago, the connection is not on the receptacle. You wrap the wire around the screw, or in a pressure clamp just like normal. When you plug/unplug something you are not disturbing the wire where it enters the Wago. So you can push/pull all you want on the plug and it won't affect the connection in the Wago. That's unlike what happens with a back stab, as you are pushing/pulling on the receptacle and the wire connection is directly on the receptacle.
Only failure I've seen with a Wago was "operator failure". And that was my install. Luckily I caught it when I energized the circuit. I just didn't have it pushed all the way in. I've been using them for nearly 10 years and no problems other than my mistake.
Note: Wago is a brand and there are other good mfg of them such as Ideal Push-ins, FPR (Gardner Bender).
I have found a new toy that I like even better than the push-in connectors. It is "Lever nuts" made by Wago. You raise a lever and insert the wire, then push the lever back down. You can feel the strength of the spring when you pull the lever up. They are especially handy when on a ladder trying to hang a light. Sometimes its difficult to hold the light and put a wire nut on the wires. With the Lever nuts, you can use one hand to both insert the wire and push the lever back down. It's best to raise the lever before going up the ladder or before you attempt to hold the light to connect the wires. Then all you have to do is insert the wire and push the lever down.
