To find the best ammunition for your revolver you really need access to a Ransom Rest. Without something like that you are really just guessing.
Also, you'll find that certain chambers are more accurate than others, sometimes by quite a wide margin. Back when I was shooting NRA pistol competition I would run my revolvers through a Ransom Rest with several different brands of ammo. I then checked each chamber and marked the one that was the most accurate. That was the chamber that I used for slow fire. The least accurate chamber was always left empty.
I found that the Remington standard velocity was the best but, as others have said, that's not necessarily true for them. Asking others will get you a lot of anecdotal answers but you really have to do your own testing.
