I'm still experimenting with it in various workflows. While I unfortunately don't have the opportunity to try it in surround, even in stereo alone it makes a noticeable difference compared to the simple BlackHole (also Eventide, it almost sounds "cleaner"). It's not a replacement, however, and this was one of the things that struck me most: each is better suited to different situations. This way, having both allows you to have a blackhole reverb in practically any circumstance. Given the quality I've seen from Eventide, what can I say... one of the most stratospheric reverbs I've ever heard
