Guess it depends on the use planned.
For serious carry, my wife has a S&W 637 with a 1-7/8" barrel, my choice is a 3" barreled S&W M36. Both are concealable, hers in a purse, belly pack, or rarely, in a OWB holster on her belt; mine is always in a OWB belt holster in the FBI 4 o'clock position. Recently, I've begun carrying a Sig P290 with a 3" tube, again in the FBI position.
For carry, daily, here on the farm, I tend to the 4-5/8" single actions, but do find time for the Commander and full size 1911's; several Rugers and one Colt, all in Tom Threepersons, open top holsters of my own construction. They're convenient, adequate protection for the gun in good wx, and quick into action against the threat of thistle tops, milkweed pods, and the occasional misguided dirt clod...ya gotta take the threats seriously, padnuh! That 4-5/8" barrel length, BTW, is as long as is comfortable while aboard the tractor, on horseback, or in the truck...anything longer ends up giving me sore ribs.
On our home range setup, I still prefer the shorter barrels, but do give the 6-1/2 inchers a regular workout in preparation for deer season. In truth, I find very little real difference in group size, between them and their shorter cousins.
For the deer stand, I choose the longer ones, 6 to 6-1/2" as a rule when using the hand gun alone. For rifle use, where the short gun is a back up, it's back to the 4-5/8" models for me. Back east, here in KY, I rarely carry while deer hunting, but in Colorado, I always have a magnum....packing out elk quarters in the twilight, unarmed, gives me the willies...fresh meat, reduced visibility, in high altitude bear country...
