What is more difficult, IELTS exam or TOEFL exam?

TOEFL is considered more difficult as compared to IELTS, because TOEFL is almost used American related Universities but IETLS is widely adopted in most parts of the world....

IELTS is more suitable for the whole native amd non native speakers 

on the other hand , TOEFL is really technical and boring test especially in the speaking part . 

it is unbeliviable to talk to a machine compared to the one in the IELTS exam.

Talking to someone gives you an ambitious and feeling that you did well or not by your own sensible feeling and being captive audience. 

If English is not mother tongue then both test have their own advantages and disadantages also...

Both of these standardised exams have their own format, guidelines and tips for success. 

Most students are trained in the format of one or two examination providers over a number of years and I think most of what makes an examination appear more accessible is the preference and exposure to that exam provider's format.

Interested to hear other people's experience after delivering both examinations as I have.

Dear Samar,   Both IELTS and TOEFL are about the same in terms of difficulty: on the speaking sections, IELTS covers a much broader range of accents (educated and uneducated, and from several parts of the world) while TOEFL is 'limited' to academic-level American (Standard) English.
So, if you're the sort of person who speaks American and who understands mostly American, then TOEFL may be easier since it doesn't include Jamaican, Welsh, Irish, Scottish, English, New Zealand, Indian or Australian accents (as the IELTS does).
  Last time I sat both exams (February2008) I had the impression that the essays required for TOEFL were more related to college-like situations (e.g.
talking for a minute or two about a biology or psychology subtopic), while IELTS covered other miliei (e.g.
talking about birthday presents you've given or been given).
Neither approach is 'better' or 'worse' than the other, but they're surely very different, and some people may find one harder than the other.
  An advantage IELTS has is that they accept both Commonwealth and American spelling; TOEFL, AFAIK, only accepts American.
OTOH TOEFL is a bit cheaper and results get quicker, so at the end of the day it's up to you.
  Good luck.
