I have nearly 8 million miles on OW, but am mostly using ST now. The OW RTW products are good but BA and AA have both deteriorated in Business. I refuse to fly BA Club because the new Club World seats are atrocious and service has collapsed in recent months. AA is getting ratty also on 767 and IB reflects their condition as does JAL. CX is still wonderful as is QX, but they aren't enough.

ST has AF, who are steadily improving and have good seats and excellent food and service. AF crews always are multilingual and ST has Aeroflot, maybe the most underrated carrier around. They're great, even in Y. Their AF/KL/SU/KE make me much more inclined to use them, and they normally are pretty generous to elite flyers from other alliances. Even SU, on invols, gives preferential service.

Lounge access and upgrades are pretty similar as are other features, and ST makes me feel valued. OW through AA totally ignores me even with all those miles and EXP since inception, TOP before that, and lots of 400k mile years and more.

Nothing anywhere matches the CX "the Wing" in Hong Kong, however, so OW will always have my Asian preference between CX and Quantas.
