Deus Ex 1: Get it from Steam or GoG?

Currently Deus Ex is on sale on Steam for $2.49, which is really tempting. However, I've had problems with older titles on Steam before, and some of those problems have been frankly rather dumb.

From what I hear GoG optimises their games better for modern operating systems.

So I'm wondering if anyone knows if the GoG version is better? Because I would rather pay more for a version that works.
