The great thing about a psychotrigger is you can elect not to use it if the situation calls for it. But if you don't have the ability to separate the aim and your release, you can't do the opposite.
That's what this comes down to. The best (in terms of accuracy only) barebow/traditional archers have the ability to separate aiming from releasing the shot.
A limb clicker, grip clicker, grip sear, tab sear, feather to nose, or some other internal trigger is not magic, and it won't do anything for you by itself. They are tools that you use to separate aiming and releasing the arrow. You do this by focusing your conscious mind on the movement to activate the trigger and let your subconscious monitor your aim.
If you can't muster the determination to solely focus on that movement, it's not doing its job. That's why Joel says it won't work for you, you must work for it.
I wouldn't expect a trigger to magically enable you to have better control over your shot overnight. It is a learned skill.
I do believe some triggers are easier to learn for those just starting out. The limb clicker is probably the best, it will also highlight inconsistencies in your draw length. I also really like the grip clicker from RMS. Both it and the limb clicker activate through movements that include increasing back tension. The feather to nose is similar, but with how I anchor, I can't really get it to work unless I crank my head into an awkward position.
The other triggers that require a different movement, also require you to monitor your back tension separate from the trigger movement. I think these are the hardest to run, especially to somebody new. It detracts from focusing on the trigger movement, which again, is the whole point.
If I were helping somebody learn to run a trigger, I would almost certainly start with the limb clicker b/c I think it is the easiest to perform correctly and with intention. After mastering that, work on other triggers to find what works best for you.
I've tried joels 'clicking with your tongue trigger', and while it can be effective, it is definitely not the easiest trigger to learn. I found that I can run it fine with a stretch band, but put an actual bow in my hands and the increased tension through my body makes it much harder. I end up not focusing on the movement, but find my mind wandering and thinking when the hell is this going this going to pop.
