Obviously, GATE exam is tougher than JEE Mains exam. JEE Mains involves the concepts and problems at the basic level (11th &12th NCERT syllabus), but JEE Advanced will be tougher.
In case of GATE exam, the questions will be based on the concepts from engineering level (from your B.Tech syllabus). So it will be very difficult when compared to JEE Mains.
JEE Advanced will be tough for a candidate who aspires to become an engineer.
All the best.
