so found somewhere still selling stuff

so, i've got a cider kit coming, I intend to have a play with turbo cider but be good to get a sizeable brew on the go.
anyway, I'm torn between bottles or keg. Now I want a fizzy finish ideally, so I've read I can prime the bottles and cap. fine. But wondered if it's easier to put it all in a keg, and add C02 - like one of these:

won't jump into a corny keg right off the bat so that's why i'm torn - long term corny keg seems the way to go and don't want to be left with a keg I don't use whereas I'm sure i'll always use bottles but at the same time, is a keg an easier route to fizzier cider?
