Hello sir, will you please compare IELTS and SAT as I want to know which is better, the IELTS or SAT??

Hey Buddy!!! IELTS and SAT are from a totally different domain
IELTS is an English language test whereas SAT is an entrance exam for various universities in US, Canada and some other countries in the world.
The SAT tests your college readiness by testing your English and math whereas the IELTS tests your proficiency in English.
So we cannot compare these two
