My FFP is obviously better than yours , and I'll clearly nominate OK+ here.
200% miles for business, segment qualification in addition to the mileage one (great if you're a short-haul flyer), lounge access+guest, free systemwide upgrades (though the very cheapest fare class is excluded), extra luggage allowances, 24-hour multilingual call centre, 1000 mile minimum for transborder flights, and visible efforts from personnel to make your travel experience that little bit better.
Only real disadvantages are the absence of an award availability checker/booking tool and the way COS bonus is calculated (before Elite bonus is factored in- e.g. 1000 miles flight in C, 50% elite bonus and 100% COS bonus only nets you a total of 2500 award miles). Oh, and non-flying earning potential is rather poor unless you live in the Czech Republic; but that's a decent trade-off for good award availability!
