Which suits you
Choose the CRF300 Rally if low-speed control and picking it up after a drop matter most: it is 23kg lighter wet.
The 390 Adventure R makes more power (45hp against 27.3hp), better for road miles between lanes, though power is rarely what you need on a lane itself.
A tick marks the better figure for green laning. Manufacturer figures; weights are wet unless marked as estimates.

Our take on each
KTM 390 Adventure R: The R turns the 390 into a proper off-road contender, with long travel and full-size wheels, let down only by a seat height that takes some getting used to.
Honda CRF300 Rally: A CRF300L with a screen and bigger tank for easier road links, still light and capable off-road, just heavier than the base bike.
Remember: rider ability, tyres and the weather on the day move the real answer more than the bike does. Check each lane's own difficulty and legal status before you ride.
