I have the Dewalt 20v and have no complaints. Plenty of cutting power and haven't had any regrets with amount of work per charge. The only negative I've noticed is the bar oil tends to leak from the reservoir. Instructions say to drain after each use, but that's a pain.
This exactly has been my experience with the Dewalt. You have to be careful how you hang it up for storage and I always loop a plastic shopping bag over the bar cover to catch any leaking bar oil. It performs great and is lots lighter than my Stihl gasser.
