Valvoline 5W40 European Vehicle has some serious performance numbers. It is relatively low in KV100 (13.1cst) while providing pretty good HTHS of 3.7 (generating high HTHS from high KV100 is easy. Trick is high HTHS and low KV100).
I like that Valvoline posts their performance numbers and do not hide anything. Castrol and Pennzoil are notorious for hiding info (and Pennzoil for generally getting their PDS mixed up).

Thanks, very helpful! Valvoline also seems to be the lowest cost of all these options. The lower cost scared me a bit but it's great to have your technical insight.
