Get a combo edge knife and try it out, that's the only way to know whether it works for you or not.
I have a personal preference for plain edge blades, they just work better for my needs. I like precision cuts, I do a lot of whittling and leather cutting, etc. However, I always have a multitool with a fully serrated blade close at hand, and I sometimes carry a serrated Wenger SAK (I find their serration pattern much better than Victorinox's) or a fully serrated Spyderco (I only own three out of a few hundred knives, since I seldom use them).
I tried partially serrated blades and didn't like them at all, I had too little of each type of edge. I even had a combo edge version of my favourite folder, the Spyderco Mini Manix, and got rid of it in record time. I'd rather have a completely PE or fully serrated blade.
My favourite blade shapes for serrated edges are hawkbills, like the Tasman or Spyderhawk, for super agressive pull cutting; and sheepfoot blades for messy utility work and sawing through things (straps, hose, etc.).
