I have been on Dreamhost for 2 months. Aside from their labirynth admin panel, I have not encountered any problems. I am currently hosting only wordpress blogs. 5 to be exact. 2 of mine and 3 of my friends. 200G of webspace a year is just plain crazy.
I have used many webhosting companies over the 15 years I have been online. 1and1 is the best. I have had 100% uptime since day one. Cheap plans and I don't know how support is. Never had to use it.
