Is webdriver reliable for IE 11 testing?

I am currently doing some automation tools evaluation for web testing.

my requirement is to run automation scripts only against IE 11.

I like webdriver but do not have much confidence using it on IE 11.

Please suggest me if are using / have used webdriver for IE 11.

Also , I would like to know if there are other options to automate IE 11.

Plus, I have tried Sahi but I do not like the editor Sahi provided .

Thanks in advance
