For us here in the UK, pretty much as the relative difference in viscosity between 0w and 10w is negligible for the type of winter temps we see.
Similarly, 30 is more than adequate since we rarely see much above that.
If you can get technical info and see the viscosity index and kinematic viscosity at each measured temperature point (40ºC & 100ºC normally), then you can see which brand is more fluid, which is better for fuel consumption and quicker to pump round the system when starting.
So long as the API Class and weight are as per the owner's manual, you'll be fine - but some oils are "finer" than others.

Better oils would be:
Mobil 1, Fuchs/Silkolene, Amsoil, Liqui Moly, Redline, Motul, than the generally sufficient big brands (Castrol, Shell, etc)
FWIW, you should also be changing oil as per the severe schedule, especially if dino oil has been used - hydrocracked or not. It's a fallacy to believe oil lasts for 12 months or 12-15K miles.
