I went from a 15" 2012 rMBP to the 13" 2015 rMBP and really like it. The lower screen size can be compensated somewhat by switching to a lower scaled resolution if you really need some space and performance is great. On paper it's slightly slower at multi-core tasks, but I haven't noticed any slowdowns yet.
