For me, that size provides a good balance between being able to pick up the dot quickly and accuracy. For USPSA, we’re talking minute of A-zone accuracy, not bullseye.
You can bump up the intensity of a smaller dot so it is quick to pick up, but for me that tends to create blooming which I find annoying. Whereas with a 5-6MOA dot I can run it a little dimmer for a more crisp dot.
As far as brands, I have Trijicon RMR and SROs, and a couple Holosuns (407k w/ 6MOA and 407CO with 8MOA ring). If Holosun would offer more models with a simple 6MOA red dot I would definitely buy them.
