The one killer feature of rollup (which parcel also gets right) is sensible and usable sourcemaps. Webpack does not deal with using Vue SFCs and TS very well, you end up with 4-5 [almost empty] files in the browser per file on-disk and often the file with the actual source is missing. You have to hunt down the correct file and pray that it is their every time you wish to set a breakpoint. I've burned days in the past trying to figure out a workaround for the unusability of sourcemaps in Webpack. Webpack has tons of knobs and levers to configure sourcemaps, but none that do what I assume most people want (a single sourcemapped file in the browser). Parcel and Rollup do the right thing 90% of the time (requiring only tweaking the path for the 10% remainder) with a single boolean configuration value.
