Using Adroll or Adwords?

I've been trying to determine whether or not Adroll is a better option for retargeting than Google Adwords. Since I've never used Adroll and have limited experience with Adwords, I figured I'd start a thread to see what you all might think if you've had experience working with Adroll. From what I've gathered, researching the pros and cons or Adroll vs Adwords, I feel like there's no contest for Google Adwords in comparison to Adroll.

It seemed like for a brief period of time, Adroll was capable of retargeting certain users better than Adwords but that is no longer the case based on answers/comments I found on Moz, Quara and the Google Advertising Community.

What do you think the benefits of using Adroll are compared to Adwords?

I've spoken with Adroll and from what I can tell their list of sites is not that much more extensive than adwords and their minimum spend starts at £5,000 per month. So, really, its not a good solution unless you already have quite the marketing budget. Quantcast seemed to be better but again they have a £5K min per month as well.

At least with adwords you're not forced to spend so much if you want to just test out remarketing!

Thanks for the extra input @RiverStyx, I've decided to hold off on using Adroll or anything other than Adwords for the time being.

I always prefer to go the direct method (AKA pay Google directly than go through a 3rd party)
