This is another tough one for me. One of the biggest oversellers in the industry but yet manage to maintain a very loyal user base.
I am not going to lie, I would never put AHFB on such an overseller. There are many websites though that would do well on DreamHost. If your website does not require as much CPU or database intensive scripts as AHFB you may be well suited here.
DreamHost has been around since late 1997 and seems to not run away from tough situations. You may not always get the answer you wanted, but they do not hide and are very friendly yet upfront.
