Hello! I am trying to decide between buying a used 2016 MacBook Pro with touchbar (512 GB and 2.9GHz) and a refurbished 2017 non touchbar (256; 2.3 GHz). I have looked all over for spec comparisons and am struggling to see which one has better performance. I am particularly interested in graphics performance as I think the CPU is probably sufficient in both. They have a similar warranty length and are fairly similarly priced (the touchbar one is about 100 dollars more). I am assuming the 2017 will have better battery due to the bigger battery and newer chipset, but I am wondering if the cooling system and higher wattage on the 2016 will more than compensate speed-wise. What are your thoughts/recommendations? Any help is appreciated!
