Securom doesn't install any driver on Windows, the DRM is on the disc.
Also, as I said before, games on GOG/Steam could be removed after few years (Wolfenstein from 2009 is a good exemple, Re-Volt is another : https://www.pcgamingwiki.com/wiki/Re-Volt
) to name a few. So yeah, good luck with all your digital games that you can lost if Gog/Steam removes them from the store.
Also, some games are not the same as the retail version, music/soundtrack can be ripped (Quake), etc.
For your information, Securom games work fine on Windows 7 and 10 (not like Safedisc and Starforce ones).
I have Stranglehold retail version on 2 DVD and works fine with Windows 10. I have other Securom 5/7 games too (The Wheelman, Reservoir Dogs, Boiling Point, Silent Hill 3 and 4.
I see that some old games in digital format are removed from GOG and Steam after a few years (Wolfenstein from 2009 is a good example), so having a disc version is always good, you can always reinstall it
The one nice thing is that even if it is delisted here, if you bought it you can still access the game (just as with most services).
I'd definitely prefer the GOG version, over having any trace amounts of those old versions of DRM out there (ala StarForce, Safedisc, Securom, etc.)
