E.C.C 6.0 is said to be the advanced version right now, in order to reduce the more code and use more  Functionality, and for high performance testing we go with E.C.C 6.0. It is said to support all type of functionalities in any conditions. More standard reports & tables, etc are available. Advantage of 64 bits is in the amount of memory that your system will be able to use. 32 bits systems are limited to 4 GB of memory. With 64 bits systems you can virtually use 18 millions TB of memory (almost limitless).So it's better for systems with high number of users, high need of memory for buffers, etc., to be in 64 bits kernel.
