Everybody is different. As for Anavar, it produces a feeling of euphoria, which largely counterbalances testosterone suppression. My friend - who has a very limited experience with steroids - said that he had never felt better in his whole life, when he had been taking Anavar. I experienced something similar with Turinabol, but not with Winstrol, after which I felt strangely deadened.
Personally, I don't understand all the testo-mania and I see nothing strange on oral cycles. Well, there are serious issues with cholesterol (not with liver values, if you take Anavar) and long-term, repeated oral cycles thus certainly aren't healthy, but a cycle with tesosterone can have far more devastating consequences, if you are extremely prone to acne or hair loss.
