I've done both of tests. It's not easier than IELTS, as far as I concern. Requires 4 hours full-time concentration.
I think it is harder to reach necessary score in Toefl than IELTS.
Note that they do not send official results to your home address as British Council does. Well, they say they do, but results are mailed from USA and it could take months to received them. I haven't received my score since May, despite my protest note to ETS! And you need them for your visa application!
