I like em both and use them interchangeably. I have 2 gyutos for every suji I have, but I started stockpiling gyutos before sujis. Since my Marko and Yosihide sujis though, I have been using sujis way more frequently recently. I think its partially because I like 270mm length blades, which in a gyuto can make for a lot of knife, while the sujis are a little more compact on the line.
