There are tons of good hosts out there….
I use resellerzoom for a reseller account so that I can host many sites.
I used hostgator for a while and they were good until my site got hacked and used a ton of resources, then they tried to force me into a dedicated server which cost a ton of money.
I use slhost with VPS now, which is nice. (also can host as many sites as I want with different IP’s if I want)
I also use site5 (no problems with them).
