The UI is very intuitive to use as it does not look like an emulator but rather looks similar enough for people who are used in other software suchs Photoshop etc.. It also allows you too change themes which can be nice if there isn't one that matches perfectly well ( I am using dark theme myself). Sometimes when viewing videos sometimes they stop working until restarted after about 5 seconds of playing them so this could need some work at fixing maybe? Haven'r really realised what else i dislike much because everything works pretty good! So far my only negative thing would have been lack off customisation options within vyosro itself though these might now come later down the line once more bugs get sorted out by developers/maintainers - otherwise its great!! Try testing both before deciding whether it fits best suit and needs of yourself / business requirements.
