UCEED is much less complex than JEE Advanced, however, you cannot really compare a Students performance in UCEED with JEE Advanced, as they are completely different Examinations and demand totally different Preparation. However, on one factor UCEED is behind JEE Advanced, thats the Competition. UCEED is far less competitive than JEE Advanced and is answered by nearly 1/10th of students appearing for JEE Adv.

hi,

see none of the exam is easy unless you prepared well. uceed stands for Undergraduate Common Entrance Examination for Design, where jee advance is the admission test  to b.tech courses in iits. in jee advance questions would be formed from physics, chemistry and mathematics. where uceed syllabus includes

Visualization and spatial ability

Transformation and/ or manipulation of 2D shapes and 3D objects and their spatial relationships

Mechanical and scientific concepts

Observation and design sensitivity

Environmental and social awareness

Analytical and logical reasoning

Language and creativity

Design thinking and problem solving

Drawing

so the preparation of both the exam is different. you have to think which of the exam you want to attempt and prepare accordingly.
