WebSQL is remarkably simple to use, works on the most popular browsers on mobile and desktop, and gives you the power of SQL. In contrast, IME indexed db felt like pulling teeth. The discussions seem to suggest that institutional intransigence by Mozilla pushed the internet back a step. (And yes, SQLite + Emscripten is significantly slower than websql on chrome and iOS Safari)

From a personal perspective I stopped building HTML web apps after I started to transition my WebSQL apps to IndexedDB. I really really disliked the experience (messy code/overhead) and haven't had any desire to write another with a client side DB again. The bright side for is however it drove me to learn iOS and Android development... not such a great day for the web though as I suspect my experience isn't unique.
