That's not to say that each of these sites don't offer tremendous value when used holistically. But if I'm being honest in my experience as a dfs player, none of them spit out optimized lineups that win frequently enough to beat the rake over the long-term (in my experience, which is a limited sample size dating back to the start of 2016).

You will never profit if you're just using the optimal lineups a website suggests. I've tried probably over a dozen different optimizers dating back to the start of 2016 including the one on here, playerprofiler, fantasypros, rotogrinders, fantasylabs, various sites on rotopass, and many others. People don't realize how hyper-competitive DK is nowadays. It's not like the commercials where you make money by knowing more than the average football fan. The cash-game grinders treat dfs like a full-time job and some of them have access to models they're paying 5 figures for annually. I would be shocked if you ever found a site for a $100 subscription that gives you profitable cash game lineups over the long haul.
