I'm sure different engine designs will vary their effectiveness, but a scraper is going into my next engine also. A combo scraper/windage tray may be more effective, but that can take some careful fabrication. As with many performance mods, there are a lot of "it depends".

In my Pontiac motors I use the Ishihara-Johnson zero clearance scrapers. They are much more expensive than the basic sheet metal ones but in my opinion worth the extra $ you never have to worry about metal to metal contact.
But an interesting comment on the Mopar stuff although it has to do with big block Mopars which use a totally different tray set up than small block Mopars; I had Allan Lee rebuild my 500 wedge a few years back and amongst the stuff I gave him to put it together was a Charlie’s fabricated pan with a screen type tray built in and I also gave him a Milodon tray as it looked to me like the pan had a lot more clearance to the crank than the Milodon tray did.
Allan left out the Milodon tray when he built the motor and told me that the dyno results on his Hemi’s showed the pans with the built in diamond screen type windage trays made more power than using the factory or Milodon louvered tray.
