Which is more your game? (Let's just say we're comparing the latest releases of each, since they both seem to represent the most advanced mechanics even though Mankind Divided technically isn't finished yet)
I think from purely a gameplay perspective Hitman is more enjoyable. Deus Ex does have more depth in terms of features, but to me they get bogged down and even the story interferes too much with simply playing the game.
The thing I like about Hitman is that you only pick your starting equipment, then the rest is up to you. No upgrades to fuss over, tedious hacking, reading emails to find door codes, etc. The gameplay is more pure in the vein of a Souls game or STALKER, but with much less monotony.
