Verdict
The clearest difference is in-app purchases: SGI at none against Google Calendar's 10. SGI also leads on iOS requirement (15.0 vs 18.0). Google Calendar's advantage is update cadence (weekly vs monthly) and chart position (#22 vs unranked). On price, ads and device support there is nothing between them.
