I've spent enough time around here and some other forums to know that sadly there is no universal astigmastism experience for red dots. It's one of these shitty click bait website but the graphic on this page is a good representation of how different the dots can look to people's eyes:

Most of the dots I use look like the graphic right in the middle but I've also found that not only does it vary from eye to eye but it varies from maker and even model of red dot. I've found almost Aimpoints look like the starburst. I've found RMRs in 3.25MOA look like that graphic on the right but MROs look like a starburst again.
For me big dots look better and more like a dot. This is great for pistols because on a pistol there is no disadvantage to a 6 or even an 8 MOA dot. Maybe if I was doing bullseye style pistol shooting where I was shooting a tiny target at 50 yards but that's not my thing. Most of my pistol shooting is USPSA or at the range and for me the larger dot has zero disadvantages. The bad thing is my options for big dot that is reliable is basically RMR. Holosun makes the 8 MOA ring which is what I have on most as it's the best compromise I can find in the sub $300 price range.
The issue is on rifles I can't really use a 6 MOA dot. I mean I can but it gets harder to use at longer distances. Plus no one makes red dots intended for rifles in anything other than 2 MOA anyway and those tend to look like a starburst or micky mouse to me.
I've tried using a magnifier and that does make the 2 MOA dots seem crisper to my eyes but at that point what I've done is make a bulkier, less rugged ACOG with more points of failure with no way to compensate for bullet drop at longer ranges. Other than cost if I *must* use a magnifier with a red dot to make it useful I might as well stick with the ACOG even if it is considering out dated.
Primary Arms has a 1x prism on the way that is supposed to be 7oz that might not suck for people like me looking for close to red dot utility on a rifle however the reticle is questionable as I often find their graphics to be misleading; they usually show you a giant zoomed in picture when in reality it isn't as big so it's actually not as useful as you'd think.
