Check the bookstore shelves if you're in doubt.
Romance outsells most category novels.
Harlequin, the world's largest publisher of category fiction, sold over 200 million books in one year. That averages out to six books per second, world wide. And they are just one publisher. That fact combined with the number of romance novels other publishers sell per year, is a good reason why slanting your work toward a category market is the least difficult way to get your first book into print. If you haven't read a romance novel within the last year, then your answer would probably miss by a mile.
