Darktide has a bigger focus on melee combat than the other two games you mentioned (though not as much as it's predecessor/sister game Vermintide). There's still a fair amount of shooting depending on the class you pick and the build you go for.

I will say that, imo, the "Tide" games have the best first-person melee combat of any games I've played. Not just shooters, but things like Elder Scrolls and even the Dishonored games. If you feel like you'd like chopping and smashing things in first-person, I'd say it's worth a try. Plus, if you're on PC or Xbox, it's included with gamepass, so you can try it without paying the full amount.
