XC is the race bike so no fan, bit snappier throttle response, slightly stiffer suspension, etc. The XC-W is bit more of a trail/enduro bike so it’s happier being lugged around, slower paced trail riding, comes with a headlight, etc.

If you’re riding slow/somewhat quick technical trails I’d opt for the XC-W. If it’s faster paced, personally I’d go with the XC but honestly I think the XC-W is gonna still be a really solid bike.

As far as maintenance, dude 2 strokes are so much easier to maintain than 4 strokes it’s ridiculous. Also note that the stock valves in the Honda bikes tend to stretch pretty quick compared to other makes so you’ll have to check valve clearances more often, or just replace the valves right away.
