I have the MK3S as well as the Ultimaker S5 and I mostly use PrusaSlicer for the Prusa, but occasionally Cura.
I have no clue where the so-called default Prusa MK3S profile came from (my original Cura came from our local makerspace some years ago) but it was UGLY! I assume that yours may be the same or similar.
The big issue was the printing speed, particularly on the first layers, which is supposed to be slower. It was MUCH too fast.
I set the initial layer print speed from 30 to 20, the initial layer travel speed from 60 to 30, and the skirt/brim speed from 30 to 20 (for the typical PLA filaments).
Cura usually has nozzle temps a bit lower than PrusaSlicer, but they seem to work acceptably well for me.
With the speed changes, there's very little visual difference between the 20mm test cubes done with PS and with Cura.
Both PS and Cura have their strong and weak points. Cura, in particular, seems to deal with supports, in general, better than PS. The 'fuzzy skin' (first in Cura) is better, but the 'ironing' (again, first in Cura) is best described, at least the last time I tried it on the MK3S, as butt-ugly, with the same function in PS being far more visually appealing.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
