I assume from this that this is your personal computer and not a work computer.
Unless you are taking this computer on the road where it is at risk of being dropped, kicked or other wise suffer physical abuse I would eliminate the Toughbook from your list of choices.
With the Toughbook you are paying extra for the hardened design and you lose speed and memory capacity because the internals were cheapened.
The Toshiba has hit the floor a couple of times over the years, which is why the toughbook was on the list. The price is within $50 for all these choices.
