I prefer to downloads because e.g. taking space on my device (which is btw also slow anyway and a specific required app was approx. at the limit of this device), other users also replied some downloads don't seem to work & generally I prefer the direct view as game playable where I'm noticing the game (on the browser) or viewable as video on youtube/streamed on discord where I could "guide" the path I'd aim for, when personally playing it. I also prefer webversions because it gets updates more quick and possible multiplayer-features being available, I also like the short waiting-duration between a "run"-click & the gamestart vs. downloading its version.
