Conversions for Citrix VM to VMware VM's

Hi

Could  someone guide me on what the best methodology would be for converting  VM's from a Citrix production environment to a VMware production  environment.

Ive used the vmware converter 5 for p2v's and have  also read that it could be used for the same v2v from citrix, some  people have also advised converting the citric vm in OVF format and  importing the same onto the Vsphere environment..

Kindly advise .
