Though one of the biggest issues with HS is that's it's TOO much control imo. There are so many settings/parameters you can mess around with but there's not much tutorial or explanation on what they actually even do. I've been trying to get the creator to simplify the design a bit...take away some of the options because 9/10 times you don't need to even use them and they kind of get in the way and make it more confusing than it has to be. DEO is much more user-friendly in that regard.
DEO also takes forever to boot up. HS when launched is loaded in like less than 5 seconds...for me DEO takes well over 10 seconds and sometimes it's been over 20. A small thing but enough of a difference to mention.
HS has no Passthrough settings at all though, so DEO clearly wins there as you guys are already integrating that into the app and trying to make it better and HS doesn't even have that capability at the moment.
