Asking which press, here or on any reloading forum, is like asking whether you should marry a barmaid or a kindergarten teacher. Personally, I do not think it matters what press you get for your first one, as long as it is a quality press. Also, there is no one press that is "best" for everyone. I really like my single stage Rockchucker, and I think it is a good press for me, at my stage of experience, and for what I want to do. Which is not volume production. But it's not the best press for everyone. Get a quality piece of equipment, and work on precision, measure everything, and be clean and consistent. if the worst thing that happens is that you end up with an extra single stage press, it's not a crisis. It's a good thing. And it will give you the experience to make the decision that is right for you for a bigger investment later.
As an aside, I like the Rockchucker, but I don't think it is that different from other single stage cast iron presses - Lee and Lyman both make a similar press. I like the cast iron single stage press. It will last a lifetime. And I am limited only by my own patience and experience.
People debate .308 vs .30-06, Remington 700 vs Winchester 70, Ruger vs S&W, and .40 vs .45. They are all good. Choices are wonderful. But it's really a blond vs brunette thing. Something else is gonna kill you, but not the caliber.
