Should I buy any of these to learn piano?
The simple answer is no. Trying to buy a nice piano without knowing how to play it is already starting on the wrong footsteps. I recommend borrowing a friend's piano (if you know anyone who has it), buy a used/cheap piano somewhere, or get a toy piano and mess around with that for fun. Fun is the key (no pun intended). Enjoying the process of learning is what's important. What would happen if you picked up a fully weighted piano and decided that the weights felt unauthentic, therefore disliked any digital pianos and gave up altogether. Start with something that costs you little so that you can enjoy the benefits more.
After learning the importance of having 88 keys, modulators, weights, and expression pedals, then you can award yourself with those tools at your arsenal.
Now, if you already know that you love piano, and that you will learn a lot no matter what, then you can save yourself some money by buying a nice piano to start with. It's up to you at that point. You could get a nord piano or something too, a nice gig monster.
