Unfortunately I don't know anything about Fuji enlarging lenses and never used a G-Claron, so I couldn't tell you which of those three would be better in terms of sharpness, contrast or distortion. But a 150mm would typically have better coverage than a 135mm so all things being equal, I'd always prefer the longer lens for any given format for uniformity of illumination. Of course it depends on how big you're printing. I don't enlarge my 4x5 negatives to more than 11x14 so I like the longer lenses. If you're making giant prints you might want the wider lens depending on how high you can crank up your enlarger head.
