If we compare the syllabus, both the exams have one key difference between them, which is General Knowledge of SNAP & Indian and Global Environment of MAT.

SNAP :

General Awareness — (30 questions)

General English — (40 Questions)

Analytical & Logical Reasoning — (40 Questions)

Quantitative Data Interpretation & Data Sufficiency — (40 Questions)

On the day of exam SNAP, students will be given 120 minutes to complete 150 questions, which is roughly only 48 seconds per question.

MAT :

Language Comprehension (40 marks, 30 minutes)

Mathematical skills (40 marks, 40 minutes)

Data Analysis and Sufficiency (40 marks, 35 minutes)

Intelligence and Critical Reasoning (40 marks, 30 minutes)

Indian and Global Environment (40 marks, 15 minutes)

On the day of exam MAT, students will be given 150 minutes & the maximum marks which a candidate can score are 200 and the scaled score is given out of 800.

The syllabus of MAT & SNAP under each section, be it English, Quantitative Aptitude, or Reasoning, is more or less the same under both the papers.

On the other hand, MAT does not feature any kind of General Knowledge or General Awareness questions, which makes it stand apart from the SNAP exam.

But you will have to study similar sorts of concepts for both exams.

However, the GK section of SNAP and the Indian & global environment section of MAT makes you stretch a little extra to crack these exams. Otherwise, both the exams are on similar lines when compared on the syllabus front.

I hope this comparison is gonna help you!
