How are you paying $90 a month at DreamHost? I could see $10 for L1 hosting, $15 for PS web hosting (128MB) and $15 a month for a PS MySQL service (128MB). That's $50 as compared to a liquidweb 256MB VPS at $60. And of course there are obvious differences between the pure dedicated storage at liquidweb and the oversold yet available storage and bandwidth at DreamHost.
The other thing that kind of makes this apples to oranges is that DreamHost is actually offering dedicated resources on a managed hosting plan rather than a pure VPS. DreamHost will manage the OS, Apache, php, etc, if you don't want to. This is a plus if you don't want to manage it - but obviously not a plus if you actually want to have root access and be sysadmin.
You still have to pay for a hosting plan. (see my example above).
