What exactly is "entry oversteer"? Understeer on entry is understandable, but "entry oversteer"?
Comes with an unstable rear axle. The back wants to swing round on the initial turn in. E.g. Locked rear axle would result in entry oversteer.
Basically the worst kind of oversteer as well. Exit is easier to control, but entry oversteer means the drive has no confidence turning into the corner so will either go in slower, or compromise his line to a more geometric shape with less steering variance.
Yeah exit oversteer can be controlled/tamed as it happens with the right foot.

I'm not sold that Mercedes has the best chassis, the RB16 is faster in slow corners, implying more downforce. Especially in long sweeping corners that don't require much braking.
Slow corner performance isn't really about peak downforce. It's about mechanical grip and setup.
With respect to general chassis performance, Mercedes was fastest in all types of corners up until the engine mode TD.
An example from Spain 2020, which is obviously one of the benchmarks for a chassis, because of the various types of corners:

After the TD, Mercedes made compromises to their setup to trade off cornering speed for more pace in a straightline. There was a pretty good technical article about this (from FUnoAnalisiTecnica) which I posted in a thread on here a while back.
With the exception of 1 race, Mercedes has been the class of the field with respect to tire management this year, implying a tremendous amount of downforce. The more downforce you have, the more you flatten the tire and generate temperature evenly across the surface of the tread, which not only helps with performance, but with tire wear as well.
Finally, Mercedes stopped developing their car a while ago, while Red Bull has obviously forged on.
Downforce matters for every single corner except the Lowes hairpin in Monaco. Also don't forget how fast RB has developed their car. It's still entry oversteer, but the rear end is much more consistent than it used to be.
Downforce puts more load on the tire, and keeps the car from sliding if the aero is balanced, if it isn't then one axle will suffer more than the other.
It was back in the 80s when Prost noted this as a driver. In the latest Kyle engineers (having just left merc) he estimates an f1 car performance in a corner. You can work back and the CzS is ~8.3 or Cz>5 depending on frontal area. That's exceeding the car weight at ~135kph/85mph.
