The more seamless experience is playing on browser, but on certain types of games, due to immersion a browser just wont do it. Also its better than executing unknown files made by strangers….

Also the browser may cause technical problems, as you mentioned.

Still I preffer to play on browser

Im much more likely to play the game if i can play it on the browser. Downloading an executable from a random stranger is risky, im sorry but it would be really easy to add viruses or malicious stuff into the game. So i advice allways doing a browser game first and an optional download if you want, unless your game is too big to run in the browser ofc.
