I'll go into this assuming you aren't going to use it for any competition speed shooting. If so, disregard this.
First off, any red dot will basically get you by. I'd go no larger than 3MOA, and 2 or 1 preferrably. People dump on Sightmark, but I've found them to be pretty good. No bad experiences for me. The TRS you mentioned is also a good one on a budget. The micro dots of various flavors seem small and all, but on a rifle that doesn't matter. You will pick up the dot quickly on a rifle regardless, so that small stature doesn't hurt a thing. Whoever mentioned the Vortex Strikefire was pretty dead on also. It is a 4MOA, but I had one on a speed gun for a while til I bought a C-More and it was an extremely good sight. Though about selling it since I don't use it, but will likely just keep it as a swap out for a 1-4X scope on an AR in the case that I want to change things up ever.
Aimpoint and Eotech are wasted on a 15-22. Why by a red dot that cost more than the gun, especially when its a 22. If there is some purpose (competition), yes, but plinking and backyard shooting, you will get by without SEAL quality optics. Even on my AR's, the Sightmark Milspec is clear, 1MOA, holds zero, and cost like $175. I've got no need personally for the Eotech. Now if I made $150K a year and had money to burn, then why not, but I'm straight middle class and can use the extra cash on some other cool thing.
