Well, it really depend on what you will be using it for.
We can't really help you properly if we don't know what you will be using the laptop or tablet for.
Is it for media consumption? If so then a tablet is perfect unless you prefer using programs on Windows.
Is it for college such as taking notes, surfing, checking emails, etc? Ehh, it really depend
If you are into taking notes, I would recommend Samsung Galaxy Notes 10.1 2014 Edition 16GB/32GB because it has the lovely S-Pen that is part of Wacom Technology. You can do a handwritten notes which it is really neat if you want a device but at the same time want an ability to do handwritten notes.
However, if you care about taking notes by typing, a laptop is preferable because it is simply better. I would recommend Lenovo because it has better laptop keyboard (IMO) and better specs (based on Lenovo's website) while at the same time costing a similar amount compare to ASUS Vivobook.
