Standardizing on combinations of developer and film is a good thing. However, what is a good combination? Do some reading first and get familiar with the various characteristics such as tonality, grain, acutance etc. Once you found your favourites, stick with those while keeping an open mind to other possibilities. Experimenting too much will only lead to confusion. Reading books by Anchell (Darkroom Cookbook etc.) helps a lot.
Personally I like most traditional film (ilford, Agfa) developed in Ultima (home made 2 bath dev)
