I would say you'll see much better performance improvements from RAM than a faster processor. Even if you just take the difference between the upgrades: an i5 to i7 could maybe be a 10–20% performance gain, whereas 8gb to 16gb of RAM is a 200% increase. Plus I think RAM is much more important for most real-world situations than processor speed. Processor speed would be most noticed during compiling.
Side note, for the love of god do not get a (non-Pro) Macbook. You will regret it. They're incredibly slow, and they only have one port.
You're essentially comparing two different generations of computer. The MBPs 2015 and earlier have a wider variety of ports, better keyboards, but no USB C, a display that's not as good, and a slower SSD. MBPs 2016 and later have only USB C ports (meaning you need dongles for any real-world usage), worse keyboards that are prone to expensive failures, a beautiful and bright display, and a super fast SSD.
