Long-time reader, first proper post, and it's about the most reliable.
This came up in a conversation recently and I realized I had no idea what the current answer was. Expect the most reliable free to look different on a weekday evening than on a Sunday morning.
Separate email and location permissions off, then worry about the most reliable free. Update photos every few months if you're active on the most reliable free.
The the most reliable free thing nobody mentions is how much timezone and schedule overlap matters.
