Verdict

The call

The clearest difference is in-app purchases: Google Keep at none against Microsoft Outlook's 4. Google Keep also leads on ads (none vs shown) and iOS requirement (18.0 vs 26.0). Microsoft Outlook's advantage is ratings volume (9.3M vs 29K) and review sentiment (64% vs 42%). On price, update cadence and device support there is nothing between them.
