Yes, I can agree with that, but I would also say that right now we have no idea how the long term will pan out. Just because the PS4 is more powerful doesn't mean it'll be the better console in 5 years time. MS might come up with some killer app that Sony doesn't have, or maybe scores some amazing exclusive games. When it comes to games consoles, power should never be the be all and end all IMO. It's a factor in the argument, not the whole argument on its own.
I would also say though, as I've said before, that just because you choose a particular console now, it doesn't stop you selling it and changing to the other console down the line. Also, I think it's a fairly rare gamer in this day and age who doesn't, at some point during the console lifespan, own both consoles. I'm getting an Xbox One to start as I know I will prefer the games that will be available, but I also know I will get a PS4 at some point.
