This is my first time seeing any of these awesome libraries linked here, but for my money I just spent half an hour reading all the intercooler docs and it looks like a winner. I don’t see the benefit of Umbrella over jQuery when you take into account the browser support and libraries available for the latter, and it seems that intercooler is stimulus + turbo links but on steroids.
These both look cool. I've learned some Vue in the past but I strongly prefer these kinds of small, self contained libraries for my Flask + PicnicCSS + very simple JS apps.
