For casual watching on a laptop/tablet → Yes,
Groups that produce these WEB-DLs don't do it for profit (usually); they do it for prestige. The fact that this file is correctly labeled—resolution, source, codec, subs—shows a level of quality control that rivals, and often exceeds, legitimate streaming apps which often buffer or downgrade quality arbitrarily based on your internet speed.
