You know what edits I like? those that don't have overdone effects e.g. chromatic aberration or other edgy shit that makes me wanna barf just by looking at it. There are simple edits that look high resolution with a good color balance that doesn't overdo effects and only use simple pan effects for transitions/before showing the actual kills clip. You can include slow mo but don't over do it.
There is also this thing called Srcdemo2 that records your demo files in any resolution you want, there is also one for CS:GO that comes with shaders or effects but I don't know where to find it anymore. It also has motion blur and some other stuff you can try out.
