What happened to good old consistency? Just pick non-retarded program you enjoy most and do it.
Every decent intermediate program is based on same basic principles. So choose one where adherence is best. For example I prefer full body vs upper/lower, because I'm lazy to train legs twice a week and my genetics for lower body are miserable. So I do full body DUP training, because I enjoy it and can adhere for long-term.
And if you're intermediate, you should know how to find volume. Go with Wernborn's rep ranges and don't overthink it.
