In practice, people often just put a "draft" of the paper on their personal website without telling their publisher. Papers in fancy journals are more prestigious, but the papers that get cited the most are the ones with full text freely available on the Web. So, when they can, scientists choose both. (The better way to do this is to support a publisher that's both high-quality and open-access and submit to their journal.)
