In general, the two hormones are almost identical as far as their 1. Anabolic effects, as well as 2. Cost($) (black market), and 3. frequency of injections needed.
As far as the QV version of the two, I liked the Cyp better. No pain. With the 250 Enanthate, I had alot of pain when compared to the cyp. Not anything that I couldn't deal with though.
