Pretty different, actually. You don't have to worry about possible malware, and you get to support the developers of games you like (aka "vote with your wallet"). Also even if you get your license revoked it's not such a big deal as in other stores, where in some cases they may even delete the game from your devices remotely, without warning. The offline installer is a guarantee for you as a consumer.

Malware is easy to avoid if you know where to download from and if you engage in the herculean task of uploading the .exe to something like virustotal.com in case of any doubts. Not like it matters much anyway seeing how there are examples of GOG games using cracks from the internet anyway.

Supporting developers is a weak argument considering that GOG's claim to fame is that they're selling old games where the development studio no longer exists or has been bought out by a corporate entity like EA.

Revoking my license isn't a big deal? I paid real money for the game.

The offline installer is about as much of a guarantee of anything as a pirated ISO is.
