I have both, as I use them in combination for a variable ND filter. But the point I want to make is that sometimes I don't check which one I grab and have never had a metering problem with my OM10/20,Kiev88cm TTL,F601,E500,E510 and D200. I do use the Cokin P series, if that would make any difference.

I have a preference to the linear as I don't have to find the "sweet spot" every time, especially for those grab shots.
