Adobe actually has a ton of competitors. Not just the one's on this post's list. They have a ton of competitors because their products span so many interests and industries. If you're looking for a paid competitor, a lot of designers choose Affinity software. Affinity offers a few products such as Affinity Photo, Affinity Designer and Affinity Publisher. Many believe their services are not only on par to Adobe's but better because they are significantly cheaper than Abode's services.
