This question gets harder to answer the more revolvers you own...
I carried revolver #1, first gun I ever bought, for about 20 years as a primary carry. Never had a "situation". Bought revolver #2 (very similar) and it ended up being the gun I had on me the two times I had a "situation", within weeks of each other. (Pray to God and knock on wood those are my only 2 times)
Both guns did their job as asked. Which is "better"?
This doesn't even count other revolvers I own that may have sentimental value, or are for sheer recreation, or just sheer admiration, or are particularly handsome/accurate, or were a grail gun, or whatever else.
That's why this question is virtually impossible to answer for me personally. All are okay by me, but none are really "I would keep this gun above and beyond any other that I own". And of course you're still adding to the stable all the while...
