I got that build of prusa slicer and tested it. I printed XYZ cube with cura and prusa slicer, on cura flow was 150%, on prusa i ajusted it to 150% manualy,here are the results:
1). Top and bottom are better on prusa slicer, but main problem i have with all prints stays same: there are gaps between walls and i can just put my nail between.
2) Infill is much better on prusa, on cura it just goes wrong
3) Walls seems good, but they seem more solid on cura

Also I reprinted default cat with pre-made g-code, there was no such problem here(exept flow was at 150%)^
