Your question is too vague. By miles infact.
You need to include your budget, and what you are looking to do.
1. Pay site? TGP? Adult or mainstream?
2. Your budget?
3. Define your knowledge of CMS's out there. As that will help in "easy" recommendation.
You simply need to narrow the field chief, or go out and piss in the wind. No offense, but it will basically be spinning your wheels otherwise. The more detail, the better people can recommend.
