Stick with your friends and the ps4. However, if you want to be the one who g ets the superior experience, go with a pc. For about 300, I've made pc part lists that beat out both the xbone and the ps4. I won't go into much detail, but what you have to consider is that microsoft and sony are about to release the updated versons of the consoles.
As for your controller situation, if you want the xbone controller, just get a converter or a third party controller with a similar layout to it.
