I have been flip-flopping since I ordered 512/16 M2 Base on Tuesday am.. Then rationalized that for 300 more, I could go pro and get the benefits , so I cancelled and ordered the Base M2 Pro. .. BUt do I need that ? would those 3 Benjis be better spent updating the M2 Base? I am on a 2015 iMac (27") now and while I run PS on occasion , that is about it .. I crunch some hefty Excel sheets, but I am sure base M2 could handle ..
