I ordered Omaha rib eyes quite a few years ok. They were somewhere between ok and good.
Haven't had any Kansas City Steaks but have ordered their prime ribs and beef tenderloins multiple times. Always hit the excellent mark. Unfortunately they priced me out of the market a couple of years ago.
Have been buying at a local meat market for a couple of years now. Less then 2/3 the price of Kansas City and every bit as good.
If you have access to a local source give it a try.
