I might be the only person in this camp, but I find the "standard" command line arguments style absolutely repulsive. I write tons of CL code, and I always use easy key=value notation (sometimes it's flag=true, which I consider to be a minor sacrifice of conciseness in favor of consistency and readability).
It is more important to follow a common convention than agree on which looks better. If you are lucky you get used to common conventions and spend no time annoyed with them. If you are unlucky you will struggle to let it go. Struggling to let go is a disadvantage.
People who ignore convention and insist on whatever they like are never any fun to work with.
