It's difficult without more background to compare.
I'm about 6', with a 30" inseam, so, I'm long-waisted.
Sitting upright, the standard windshield, at MAX height is just below my line of sight.
I opted for the Clearview +4. It's 3" wider than the stock windshield also.
At it's lowest setting, I can see over it quite well, and at it's highest setting, it provides excellent wind protection, as the highest point is just about at my forehead top.
I have not used any other brands, so I can't comment on them as a comparison.
However, compared to the Standard shield, it's like night and day.
One thing I've noticed is that, recently, Tulsa has come out with an adjustable +4" windshield that strongly resembles the Clearview +4, including the adjustability.
That says alot in my book.
I love the Clearview, and when looking thru it, it looks like my auto glass.
