The useful differences are in your hands
Ohio’s 28.5 mm shaft, smooth centre and two sets of grip marks give it the broader brief. Ohio Power’s 29 mm shaft and coarse, knurled centre put its priorities on the three powerlifts. For a garage gym with one straight bar, the Ohio is the more versatile choice; a dedicated powerlifting space has a clear reason to choose Ohio Power.

The stainless finish is part of this comparison
The quoted products differ in coating as well as bar design. This Ohio is E-Coat with bright-zinc sleeves; this Ohio Power has a stainless shaft and chrome sleeves. If a sale listing uses another finish, its price is a different configuration. Keep that distinction when deciding whether the premium buys a design you want or chiefly a finish.
Rogue Australia lists the stainless Ohio Power linked here. The E-Coat Ohio source is Rogue US. Use those exact listings to establish the package and delivered cost. Rogue’s published tensile-strength figures do not establish which bar fits your training, and neither bar needs to replace a suitable one you already own.
