The article (especially the mention of Bower and Foundation) makes me curious, but I don't have time to try things out. Does anybody know how Sprig compares to Timber?

FYI I usually build my websites with http://Bolt.cm , a next-gen cms that also uses Twig, but if WordPress is unavoidable (some clients kinda demand WP), I have used Timber occasionally, which works a lot better for me than having to build plain PHP loops.
