Which one is easier (IELTS or TOEFL) and requires less time for preparation?

Hello!
I hope you guys are doing well. I intend to give IELTS or TOEFL in December but I can’t decide till now. Which one is difficult especially reading and writing sections of both TOEFL and IELTS? I am struggling to make a final decision. Any help will be appreciated.

Look at what exam your selected universities requires then calculate which exam is accepted by the majority and take that. If the universities are comfortable with both then up to you to decide as both exam differs in their structure . Also, look for the after cost (how much money it takes to send scores ).

The universities that I shortlisted accept both.
I want to ask you a general question.
How will you rate the difficulty level of TOEFL to GRE? How much time will it take to prepare for TOEFL after GRE preparation?
