Why people actually use those clunky web-based tools is beyond me. It's like using a normal design tool but worse in every conceivable way.
It doesn’t have the versatility of KiCAD but is lighter and easier for light use or occasional design of moderate complexity.
Footprints are a point in EasyEDA's favor, but in simple circuits, almost all footprints are universal. If you want a 10K+5% resistor, you just put in a 0402 (maybe larger if you're planning on hand soldering it) and pick the exact part afterwards.
