I prefer Dewalt simply because I have several Dewalt tools and plenty of batteries.
Same here. Back in the day, everything I had was gas-powered. I got tired of the maintenance, fuel that goes bad over time, changing spark plugs and all of the rest. Now everything I have is Dewalt - from work lights to air pumps to lawn equipment.
I have a Dewalt chain saw that is about 12", which may be the 300mm you are talking about. I do not use it much, but like all of my Dewalt products its been 100% reliable. Just keep it topped off with chain lube, and adjust the tension from time to time. I don't know of any reason not to get one.
