Don't listen to the other guy, he's obviously a mayavadi.

Whom were u refering and what did u mean from it Mr Kyros?

ANY WAY COMING TO WHO IS GREAT sHIVA OR VISHNU-I mean wo are u to conclude that?
Its not a rational aproach sayin that some purana's say about shiva so it i sshiva and some say about visnhu so it is visnhu-In dat case Namakam whihc is a part of rigveda (not secondery purana's) says about Shiva as supreme and in sama veda speaks about narayana.

A real vaishnava will not speak so.Why did Rama worship shiva all his life??
We should just see these names as different power's-No power is abvove
