i dont play other games with slides, sprint etc etc but apex does source movement very well, very in depth, lots of engine manipulations to do things like mantlejumps, or advanced lurches etc etc.
as for things like sliding in any direction, you can easily accomplish this in apex by transferring your momentum with redirects, lurches, etc. apex has very fluid, almost combo like movement, similar to something your would see in other janky ass movement games like tf2, quake, melee, etc etc.
I highly recommend checking out the apex movement wiki to learn more about apex's movement if you are fan of the classic, arena shooter style of WASD movement. apex absolutely shows it's source engine roots.
there are many valid criticisms of apex (EA is horribly greedy, awful micro transactions/in game items, the fact that its a battle royal and much more) but the movement is fantastic and largely the exception to a point i would otherwise largely agree with.
