The C&O can certainly be less enjoyable than the GAP, particularly in wet conditions. However, the history along the way is worth experiencing, at least once. Sections of the Towpath have, in fact, been improved. As noted in an earlier forum thread, the section between Shepherdstown and Brunswick has been resurfaced and is much smoother and with better drainage than its earlier, natural condition. I'm told that another section of the Towpath downriver from Brunswick has also been similarly resurfaced.
Also the WMRT that parallels the Towpath is a very nice, paved trail.
So, I guess it depends on your tolerance for some mud, roots and rocks.
