I have .357 Rossi 92s, a .357 Winchester 94, and .30-30 Winchester 94s, and .30-30 Marlin 336s. They are all great, and I would call them equal to 125yds, maybe 150yds. But I trust my .30-30s out to 225yds. Both are good calibers, but the .30-30 uses a longer (higher BC) bullet of close to the same weight, and slightly higher velocity. So to me, there is no advantage to the .30-30 until ranges start stretching beyond 150 yds. Inside of that, the .357 does the same job for me while burning about half the powder to do it. The nice thing about the Rossi, like has been said, is how easy it is to fit a bullet to the slow ROT. All my leverguns are good for 1.25-1.5"@100 when I do my part, but 2" normally, regardless of make or caliber.
