Ideally, the best package that you could have is getting it with a discount, and obtaining it with an offer is far better than getting it at a regular price. If you are going to get it, the best thing is to get it with an offer, right? Comparing the previous offers like what others said, it's not as high.
X and s are almost the same and they have the same security. The only advantage x has is the extra memory space, so you can have more altcoins apps installed at once (which is not q great advantage )
One great advantage of X is the portability and no need to bring the extra item (cable), and you could just use it with a smartphone, and you can transact your crypto anywhere. This may be a little thing, but X is convenient when reading the transactions that you have like the address you are sending it to. It shows in 2 lines, instead of moving one-liner in S. It's quite annoying for me.
