I suspect the same argument would apply to Petro-Canada's Duron 0w-30, although I'm not certain about its pricing, but I suspect it's competitive with Imperial Oil's offering.
The HDEO 0w30s you mentioned are very fine oils, built with above average basestocks vs your average GF-6 or mineral HDEO. For robustness, they will always trump the EC/RC range.
But sometimes, one does want to limit HTHS, especially in commuters. EC/RC GF-6 10w30 is not an HTHS superstar, but it's about as good as it gets (generally) with an EC/RC rating.
The risks of overheating or running hotter than normal during summer, especially in power dense engines. is more of a concern than experiencing unseasonably cold weather where I'd want a 0w in the pan during July.
Therefore, 0w30 Synthetic HDEOs while quite robust, the grade itself is something I do not need in the summer. I would rather an equivalent synthetic HDEO 5w30, or dare I say it, 10w30. Just my personal preference.
As molakule has pointed out (and I'd hate to use his example for my case knowing he does not agree with much of my rationale) but those synthetic HDEOs would be blended with a carefully selected base oil mixture/ratio specifically chosen for a 0w rated 30, again, not design parameter I'm looking for in a summer oil (but come winter, definitely something I'm looking for).
I've got no problem with people using high quality 0w's all year round as a point of convenience; that's a selling point and great help to some consumers, but I would never select FOR it when not required, personally. I'd just prefer to fuss about getting the absolute most tailored oil selection possible for the conditions- hence being on BITOG
