I have only tried revant and fuse. Revant couldn't do progressives and Fuse can. I have not tried IKON.
I agree the grey base isn't the best choice, but for me it was grey base or no x-metals, so it's an easy choice. If you don't need progressive then Revant may be a better option if they have different base tints.
For me the turn around time and customer service from Zach is what sold me on the Fuse lense.
I’m leaning towards fuse. Ikon doesn’t make ex right?
