I like both - they're tools which each have their place in the creative universe.
Everyone's previous comments on this seem spot on with my own experiences. One thing that hasn't been mentioned yet is that if you are an illustrator working the indie market with self-publishing author clients, you won't necessarily have more control, you will simply be controlled by someone who most likely has less experience than traditional publishing staff, and the work's quality may damage your reputation in certain areas. Will Terry's YouTube channel is a great resource for advice in working with self-publishing clients.
But let's say you're an author/illustrator and it's a niche market book for a highly specific audience - that's one time Indie may be better than Traditional.
It really has to be a good fit for either tool. Unfortunately so many people go Indie thinking that Traditional publishing is stuck up, when in fact it's more about quality control and potential sales. I'd say Good Indie doesn't avoid the teachings, if you will, of Traditional - it should not be an "easier" path, but a freer one.
