The AT is shorter, easier, with hundreds of shelters to get out of the rain in, usually ez to get water, (as many shelters are located next to springs flowing out of a pipe lodged into the hill!) & food; more towns to get a shower in; more trail helpers (angels) to help you out with rides etc… more other hikers to talk to & learn from; more places to buy gear if yours turns out to be too heavy or unreliable; you really can mostly just follow the white blazes, so mostly just need the databook & philosopher’s guide to trail towns if that is still around & perhaps some maps, especially in the wildest parts of Maine. If you buy food cheaply at home with triple coupons, you can have friends send your dried foods & replacement gear like socks/ new trailrunning shoes or lightweight boots (hike ultralight if u use T R shoes & replace them every month or 2 to preserve the muscles)…
then you take the large box of food from home, with a smaller box or 2 in side to forward some supplies ahead a week or so. Many hikers get specialty foods sent from home & buy oatmeal & other common items in town… or you can shop in large towns & send food ahead to small ones along with gear you might not need like winter gear … this is called a drift box & if you send it priority 100-200 miles ahead (depending on how fast you hike), it gives you the right to forward that box (by a note or postcard or phonecall to PO) to the next trailtown at no charge.
If you still must do the CDT to be the youngest, then take a GPS & a copy of Ley’s maps if he’s still helping hikers at phlumf.com? & some general roadmaps if you have to get off trail… it really helps to have several pairs of eyes to watch for the turnoffs, as I got lost when solo hiking CDT so many times it ain’t funny, & like most trails in the US, Europe, Australia etc… the important junctions are almost never marked, while obvious trail is always marked (don’t ask me why in the US, or Europe, but it’s park policy in Australia to hide the trails). Be ready to carry 5 liters of water or more at times on CDT, sacks from boxes of wine can be used, while AT has very few times when alot of water must be carried except during droughts. Bon Courage, Grande Randonniste!
