Regarding AZ's post, I did a quick search. These are mostly for 2020-2021. I kinda took whatever came up first in the search. Some are gun sites, some are not. I was too lazy to format.
Not real research, but as a quick and dirty, I suppose you can look at the states that consistently come up somewhere in each list.

3. Alaska

2. Idaho
The big news for gun owners in Idaho this year was Governor Brad Little’s signature on a permitless carry bill in March. Permitless carry was already legal for Idaho residents, but this legislation extends the law to cover all U.S. Citizens over the age of 18 to carry, including in the cities. With this slight change in law, Idaho ties the number one state in terms of points. (2019 rank: 2)
1. Arizona
No relevant outcomes in 2020. Arizona remains number one on our list due to its thriving competitive shooting scene and firearms industry presence. (2019 rank: 1)
