In my totally subjective experience, the reduced power consumption of doing away with Google Spy Services exceed whatever background drain I've suffered with 3+ apps doing their own messaging for notifications. My phone (Moto G5 Plus) has been off the charger for over a day now and is still at 65% battery. As for reliability, I have notifications for email (using K9 Mail and IMAP idle), XMPP (Conversations), and Signal. Emails (using IMAP idle) always reach me within a second or so. Occasionally, Signal messages will take hours to reach me, but I suspect that's not a problem with the websocket connection to my phone, as others running Signal (on a Google-laden phone) have had the same issue.
