Serrations have their place in my world of things that need cutting (strangely excluding all food prep - serrated knifes are banned in my kitchen). If I know I am going to be cutting a lot of rope, vegetation or plastic (or similar synthetics) and it doesn't need to be pretty, I'll always take a fully serrated blade. Underwater work - only serrated works for me and a dedicated Atlantic Salt lives in my dive box for this.
Having said all of that, I generally prefer plain edge for my day-to-day EDC tasks and my "full" size EDC is generally plain edge but a serrated Ladybug lives on my key ring in case I need some teeth.
Combo edges are, in my opinion, a compromise that doesn't work. I have some but very seldom carry them. I prefer to have my "full" size plain edge and a serrated Ladybug with me rather than a blade that isn't sure what it is. You cannot be half pregnant (or half serrated).
