Your D3300 is more than capable of making great images in 95% of what hobbyists will shoot. I haven't heard of a "bad" camera made in the last few years. Everyone seems to bringing something cool to the table. Fuji has been tearing up the compact camera market with the XT-1, x100T, Etc. Sony has a full frame mirrorless camera,I think Nikon has the best body out there with either the d3x or the 800 line. Canons best development in the past few years has been their kick ass zoom lenses: like the 24-70 f/2.8 Mark II, the 16-35 f/4 iS, the 70-200 f/2.8 IS Mark II, which is so dammed sharp it sleeps on a cutting board.
