Up until somewhat recently, my kitchen knives consisted of the now battered set I received at my wedding and the plethora of fixed blades and pocket knives I have at my disposal. I favored the latter two options over the former.
However, I recently took the opportunity to have a trio made (actually, I bought one and then ordered the other two to match). The set consists of a Gyuto, a Santoku, and a petty knife. Up until now, I had never given this handle design any thought or consideration, it always appeared uncomfortable. However, after experiencing it in hand, I have to say that I am a fan. I don't usually like my hands to be locked into any sort of grip and the long handles and octagonal shape provide me with a lot of versatility without sacrificing any security.
Also, my wife is a huge fan and that is a big plus.
After hearing Nathan's thoughts on a good steel for a kitchen knife, I kind of regret my steel choice on these but they are ground very thin and maintain a great edge for a good amount of time - I just have to strop them now and then. Tasmanian Blackwood, with African Blackwood bolsters and CPM-20cv steel.
I favor the Santoku and the petty knife - between the two of those, I can process a lot of meat and veggies in a short amount of time. I like the height of the Santoku, it just glides through everything and it definitely suits my style of food prep. I might be able to more scientifically dissect my thoughts after reading some other opinions here but for now, this will do, I guess.
