Yep, that's a beast of a delay. I don't know of any delay plugin that'll top its functionality. Pretty crazy how far they went with that, especially for a stock effect.
I use various IK Multimedia effects on every one of my productions. The plate reverb in their Fame Studio plugin is my go-to plate for vocals. For bread & butter hall and room reverbs, I've been using their CSR plugins for many years because they are insanely editable. I often recreate vintage music, so I've gotten plenty of use out of their Roland Space Delay and Tape Echo. For all other delays, I typically use the stock Cubase plugins. I also get a lot of use out of Valhalla Shimmer.
