Does LUN size/ #VM per LUN matter?

Hi
Have 4 ESX hosts share LUNs on one Equallogic Ps6000e 3 Tb usable storage.  
Just trying to size LUNs the best way

How does it matter in this situation how big or small I size the LUNs or how many VMs are each LUN when all the LUNs connect to all the ESX hosts and are are on the same set of 12 spindles of the arrary.  Each ESX host has 4 ISCSI connections back to the arrary

We use 500 GB luns, you should keep about 20% free of space for backup snapshots.
The number of virtual machines is not that important.

Just a remark, a snapshot is made to create a deltafile of changes of the original virtual drive during the backup. A snapshot IS NO backup solution itself.
