I've always bought oil based on price, so there are some oils I haven't tried.
Which oils do you want to try?
For me:
Euro oils: Castrol 0w30 and the new Mobil 1 Full Synthetic 0w40.
Both are lighter than the old M1, Castrol 0w40 and Ultra 5w40 which I have used.
API: Pennzoil Ultra, Mobil 1, Mobil 1 Extended Performance, a very high VI 0w20, Platinum 5w30
Have used or bought Motorcraft 5w20, Synpower 5w30, Quaker State UD 5w30, Pennzoil Platinum 5w20, Castrol Edge 10w30, Castrol Synblend, AFE 0w30, Edge 5w20
