I have only grown Nirvana's WR and I thought it was execellent. They have been producing this strain for a long time. Here is a pic at day 37:
No doubt other breeders strains of WR are good as well however don't discount Nirvana's because of the price.
only one worth getting is mr.nice medicine man/white rhino. trust me don't bother with any others, this IS the real deal. good luck with yours mate.
