@jack You and me both!
I think it's help to recognize that we're trying things out, and budget time accordingly. Too often, I used to jump in to an app thinking I'M GOING TO COMMIT TO THIS NOW AND IT IS GOING TO MAKE THIS WHOLE PROESS SO MUCH BETTER!!!! With to-do apps, they'd FIX MY LIFE.
Now, I'm more aware that I'm just trying this thing out, and maybe it'll be better than what I'm already using, and maybe it won't and either way it's fine. Then when I'm done, if the new app doesn't look worth a switch, the toys go back in the toybox.
In this way I have several times resisted the urge to switch from Things to OmniFocus and back again.
