I have been collecting counter-offer stories from a small network of mid-to-senior engineers over the last 90 days. Twelve of them ran a real counter-offer cycle in that window: their current employer learned they had an outside offer, presented a counter, and the engineer made a decision. Of those twelve: Four took the counter and stayed (good outcome — money up, role intact). Three took the counter and left within 6 months (bad outcome — money up, but the role got worse). Five rejected the counter and left for the outside offer (mostly good — clean exit). This post is the comparison between the four "good counter" outcomes and the eight that didn't go well.
