Description

Comparison of UI systems in UnityChoose a UI system based on the type of UI you need to develop and the features it requires.
UI ToolkitThe latest UI system, designed for optimized performance across platforms and inspired by standard web technologies. Use UI Toolkit to create extensions for the Unity Editor, and to create runtime UI for games and applications.
uGUI (Unity UI)A GameObject-based UI system for developing runtime UI for games and applications. uGUI uses components and the Game view to arrange, position, and style the UI.
IMGUI (Immediate Mode GUI)A legacy, code-driven UI system that uses the 
OnGUI
function to draw and manage UI. Use IMGUI to create custom Inspectors for script components, extensions for the Unity Editor, and in-game debugging displays. It's not recommended for runtime UI.
