I feel I've tried them all. Echarts is the best overall charting library. Fast, complete, easy to start, advanced options, looks great by default, good examples, server and client rendering, SVG and canvas. My only complaint is the chart-data data structures. Each chart type takes a different structure and axis data structure. They bolted on a data table feature (columns and rows), but it's not as documented and last I tried, incomplete.
