This is probably not the easiest "framework" (not sure this is a good name for it) but it was very fun. I think, if I had to progress from just a toy to a really strong, user facing UI, I think it would still be a pretty good choice. If some feature is missing, or something doesn't work as I would have liked, I know it will not be difficult to correct it myself.

I know that this could feel overwhelming, but this is freedom in a world where you expect there exists a single "best practice". As long as the tool is powerful enough it will be fine. On my end, I appreciate the fact there is not a single "web framework" in Clojure. Instead you have tons of libs you can use that work well together because they are all tied with a few common concepts (like ring for example). If you don't like to choose the libs. There are a few people that provide a starter pack with somewhat nice bundle of libs in a single system like pedestal or luminus for only citing two of them.

My recommendation is to not lose too much time looking for the best choice. Most of them will be good.
