It comes down to your host, their servers, what kind of traffic you'll be getting, whether your linking to FHGs or storing all the content on your hosting, etc.

I use Hawk Host for all of my shared hosting accounts (except for 1 account that I have with Croc Web) and I've had nothing but good experiences with them. I saw all the good reviews they were getting on WHT and other hosting forums so I started my blog network with them awhile back and I'm glad I did.
