Certainly decent enough to consider trying to setup a EU profile on a US console and grab PS+ for a year. Maybe get some nice double plat stacking too.
How would you get stacking platinums? Don't you have to use different accounts to have both EU and US PS Plus at the same time? If not, I am intrigued. Also, even if you can use the same account, I don't see how you could get a second platinum just because you got it EU instead of US. Maybe I am reading too much into your comment and you are just saying you could have a platinum for each user ID.
