I usually prefer plain, but acutally i carry a serrated blade pretty often as well, especially for sailing. CE ist a good thing too. in a nutshell, i use every type. I like plain for a nice, polished edge and more precise cutting, serrated for the aggresive egde and EASE of resharpening (it's way easier and faster than a plain edge or even a CE) and i like CE for having both options of cutting. it's a PITA to sharpen though. not really hard, but it takes really long cause you have to change the setup all the time.
