AILET is a tougher exam compared to CLAT. AILET is held by the National Law University of Delhi while the CLAT exam is for admission in NLUs, IP University, and many more.
Reasons:
AILET is a cut-throat examination and chances to get a seat in NLU Delhi is minimal. Around 17000 candidates apply for the exam for only 80 seats thus, the difficulty level gets higher every year.
In CLAT, almost 18 students compete for a seat whereas, in AILET, there are around 203 students competing for a seat in NLU, Delhi. Although the same students who apply for AILET also apply for CLAT, the competition to get admission in NLU Delhi is tough, since it is one of the top 5 National Law Universities in India.
