You'll notice that the viscosity spec's for the SN oil are indeed different to the SM version:
KV40 44.77cSt
KV100 8.466cSt
VI 169
If the MSDS figures are correct, their are other 0W-20 oils I'd choose over the Idemitsu SN GF-5 0W-20.
Out of what I'd say are some of the more common and shelf available 'SN' 0W-20 oils, what would you chose in what order? Mobil 1 AFE 0W-20, Honda 0W-20, Toyota 0W-20, Mazda 0W-20.
For me its consistent non-rebate prices that sway my decision, a couple weeks ago I took advantage of Oreilly's $5.49/qt for Mobil 1 and bought 6 quarts AFE 0W-20. Walmart around here has 5qt jugs of AFE for $26.48, single quarts at $6.47, I need 6 quarts for the cars I service, so in effect(26.48+6.47)/6 = 5.49/qt plus tax. However, I've found that the Beck-Arnley/Idemitsu 0W-20 is $5.72 on Amazon. If the Beck-Arnley isn't any better than the AFE I'm using right now, I will stick to AFE, but I could save some tax buying via Amazon versus Walmart, just have to wait a couple weeks for it to ship. Going Toyota/Honda around me is hard to do when the dealer wants more ($6+ per quart even on a case quantity) for the oil than I can get AFE for.
Edit: D'oh, just noticed you're in Canada so your options are quite different than ours.
