I use these three plugins very often:

1. Imperial Delay by Boz Digital Labs which currently has a 55% discount  https://www.bozdigitallab...roduct/imperial-delay/
2. Replika XT by Native Instruments  https://www.native-instru...te/effects/replika-xt/
3. H-Delay by Waves https://www.waves.com/plugins/h-delay-hybrid-delay#delay-on-drums-electronic-music-production

- Outer Space by Audithing is also interesting  https://www.audiothing.net/effects/outer-space/
- PCM Native Effects Plug-in Bundle https://www.audiodeluxe.com/products/lexicon-pcm-native-effects-bundle  with these plugins I worked in a studio and they sound great, on the negative side they have a high cost and require iLok.

More seriously , UVI relayer is dope , and for those that went traction boat , they have a delay in the essential suite that is excellent .

This is also really nice: https://www.pluginboutiqu...Delay/4178-SphereDelay

I'm just getting into Replika XT now (didn't even realize I had it, lol). It's an incredible delay, on par with Echoboy. So much you can do with it in terms of shaping the delay to fit in the mix (as well as completely mangling it for special FX). Probably a little less daunting and more user friendly (and modern) than Echoboy as well. If you could only own one delay, you could definitely do a lot worse than this.
