Hello, I just brought Macbook Pro 13", 4 thunderbolt 3, 16 GB/ 512 GB. It cost me $2199. Macbook Pro 15" is $2399. Now I am confused between these two. Should I return upgraded 13" and get entry level 15" or should I keep upgraded 13"? Which one will be better for years to come? Please help me on this. I will use this Macbook for programming and for some other work related to blockchain development. I don't do any photo or video editing. Please help me to get the best Macbook for my use case.
