It really depends on how deep you want to grab later on in your pocket, if you need to get any repair or upgrades done.
Both models are the least upgradable/repairable Apple laptops as of right now.
128gb SSD gives you enough room for OSx, some programs and updates, unless you are shooting for external drives.
8GB ram - better than the base model with 4gb.
I just hope, you are going to get 3 years of Applecare, otherwise you'd be looking at similar amounts to get it fixed as what you initially paid for it(if something goes wrong....)
