Unity is beginner-friendly with a vast asset store, making it great for 2D games, mobile games, or smaller projects. Unreal Engine 5 offers top-notch visuals and performance, ideal for stunning 3D games. However, it requires more expertise due to its C++ coding and complex interface. Consider your team's skills, project type, and desired graphics level to make the best choice.
