Not really. Canon mirrorless is ok, I suppose, but very much a "also-ran" and "too little, too late" in the very competitive market. Nikon mirrorless are just not very good (too small sensor for a start..)
I have a Nikon 1 and I'm pretty satisfied with it. Key features for me were small package size, low weight and fast shooting (10/20fps with phase-detection autofocus). My use-case is being able to take some decent bike-action pictures with a camera that easily fits in a backpack. For other usecases the offerings from the other brands might be a better fit.
Canon's EF-m lenses are a fraction of the cost of Sony's. Sony have been pushing price points for a while to make sure they are at the top of the range, just slightly below boutique manufacturers. Meanwhile canon has a lot of experience building to a price point ... Interesting to see they chose to go down that route with their mirrorless system.
