Absolutely. The quality of other's solutions and the more Clojure centric atmosphere are pluses compared to for ex. HackerRank. The reason why I personally chose HackerRank over 4clojure was the Ranking/Badge/Percentile central theme. I just got hooked on competing with other people and upping my profile. Though now I am thinking I should give 4clojure another go..
