If I were to work mostly alone on a smaller project, I would use clojure/clojure-script, because I used it at my work for a year and really liked it.
If I were to work with more people, I would first ask them.
Do they have dislike for dynamic typing? Scala+Play sounds good.
Are they really comfortable with EE java? Spring MVC + Hibernate + JSP ... e.t.c
