For alt. processes usually the first consideration is paper. Often there are good papers for a process that cost less than Platine, so more expensive doesn't always mean better. I personally prefer Platine over Cot320 as it is a little smoother to my eye and I think a little less expensive, though I keep both in stock.
Also having a variety of papers that you are familiar with provides some versatility with how a process will look and perform. After a while you will have your favorites.
