Targeting radar of S-300PM (and consequently of S-400) i.e. the 30N6/30N6-1 has a Field Of Vision (henceforth FOV) of 120 degrees as normal for any ESA radar but is mounted on a steering plate that can be rotated 360°.
Organic to the system there is however also the 5N64S search battle/management radar made off by two opposite dish plates rotating each 180° so to to complete the complete scan in less time.
All those radar are mounted as all the other components of the system on high mobility trucks and are able to be set up in a matter of minutes.
Patriot radar concentrate all those functions on an unique radar, so it was surely more sophisticated.
There is just this little, secondary problem that said antenna is not rotating at all and STILL NOW moved with a trailer so if a target is coming outside that F.O.V. or even worse is coming from different direction at about the same time they have to shut off and put the radar in travelling mode, attack the trailer to a truck mover , change the facing, unlock the trailer, fixate it to the ground etc, etc...
S-400 use still the some TVM missiles inherited by S-300PM series but add also ARH ones beginning with 40N6E and 9M96, same with radars, some components are PESA Hybrid, other AESA from the initial introduction of the system.
I will give you however a (partial) satisfaction: original version of Patriot was in the overall,SUPERIOR to the first versionS
of S-300 (i.e. P to PT), TVM from the beginning, one radar able to do both search that targeting, less time needed to be put in function etc, etc...
What you have not ABSOLUTELY not understood (in your default, always turned on, male reproductive organ measurement functioning mode) of my own post is that at a certain point, a very early one i must add, they concentered all their modernization efforts of the Patriot almost exclusively on the ABM defence role of it.
This allowed Soviet to overcome the initial shortcomings of their own system, that were motivated by their initial lower level in some key technologies necessary to implement the great development potential of their own design through successive, constant series of refinements and upgrades.
I have also said openly that one of the leading reasons that lead to such an outcome is that american though to address the inherent, structural shortcomings of the Patriot adopting MEADS and the failure of such a program left them in actual dire straits.
S-350E is instead designed to deal specifically to those all trough the horizon waves attacks NATO is planning to try in order to overcome current russian generation, perceived
more than real weak points.
It would however doing it by integrating with those system, in order to counter a specific menace not by replacing them.
