It really personal preference on the helmets. Each manufacturer has its own color, and are all slightly different.
I found my eyes like a blue green color lens much better than orange or yellow green. I found this by trying many different brand lenses in my Jackson fixed shade helmet.
The only auto dark helmet I have found with similar color is my Jackson w70 bh3. It is very blue compared to others.
Lincoln/viking are very nice for the money and are a deep green.
Miller are a more yellow green, similar in color to 3m speedglass.
I have a jackson, 3m speedglas, Lincoln viking, and a miller's auto dark, and a Jackson fixed shade with a gold coated #11 green lens.
The 3m headgear is the best, and has side windows that are great for confined space work. I'm not a huge fan of the color, and these are expensive.
The miller/Hobart is a good helmet but not great.
The Lincoln is better than miller in my opinion as the color and clarity of the lense seem better. Headgear is about the same.
The Jackson autodark ha the best lens by far, but is pretty expensive, but the Headgear sucks badly.
If I were buying again right now, I'd buy Lincoln viking, or Jackson.
There are cheaper Jackson auto darkening helmets with smaller lens sizes, just make sure you get one with the balder technology to get the super clear lens.
With all that said, nothing offers the clarity of a fixed shade glass lens.
