Serrations will not chop as well as a continuous plain edge. Serations are great for cutting cloth or rope, fibrous fabrics etc but that's about it in my experience.
Most of the time (apart from Kershaw's seration pattern) they are VERY difficult to sharpen effectively, that's assuming the design allows you to bring an edge back up in the first place.
Most of the chopping will be done with the front 1/3-1/2 of the blade so you will notice it more when batoning. If you're going to be doing multi-day backpacking I would suggest that you also take weight into consideration. Not so much for the way there than for the way back.
