Ive run both.
My favorite cycle I ever ran in my life was Test Prop 100mgs ED/Primo (schering) 100mgs ed and I wanna say 30-50mgs of anavar daily. Ran it for 3 months, cost a fortune.
Super smooth, my moods were great, nice lean small but hard gains. Super user friendly and effective.
My only concern is that I feel alot of the Primo on the market nowadays just is not that great. I also feel that way about anadrol.
So ur call man, good luck.
