With Marvel, we know all their shows are connected, not only to each other, but likely the MCU as well with Agents of SHIELD likely being the glue in the middle.
DC's offering seem like a bunch of random shows, possibly from different time periods with only 2 of them guaranteed to be connected at all, and we're not sure if any of them are connected to the DCmovieverse.
So I would argue that while DC/CW definitely has a better TV show at the moment, and are expanding on the Arrowverse, Marvel definitely appears to have it more together as they actually have a plan and are executing it.
The Avengers build up at the Movies, The Defenders build up on Netflix and Agents of SHIELD on TV. Marvel is going somewhere. None of us are quite sure what DC is doing or where they are headed.
