What are you shooting? I love Canon for its versatility indoor and outdoor so easy to adjust.
Nikon lenses can't be beat though and are amazing for studio work and all around people stuff, not as versatile as Canon though.
I bought one of each ... I carry the Canon every I go for textures (photoshop) and general purpose outdoor shoots.
The Nikon is my go to for the studio and portrait shoots, even outdoor controlled shoots the Nikon is great.
