I use it a lot of the time (Sekonic L308s), and a friend, an Ilford Artisan partner who taught me developing and enlarging insisted on me using it to get the best possible exposure for printing. He uses one almost exclusively.
As my spot meter is so temperamental I also use the Sekonic for large format, with no obvious issues.
I'm not a fan in very poor light with very small areas of light that might lead to the incident meter underexposing the subject (worse with pushed films). There I will use a built in camera meter.
Leica M2, Nikon D700, Bronica RF645, Leica CL, Summicron 40mm, Rolleicord Va, Hasselblad 500 CM Zeiss Planar, Leica 50mm Summicron V3, Hasselblad PME51 metered prism, Zeiss Ikon Super Ikonta 534/16 & Ensign 820 Special - all gone.
