I've just got a new XPS 15. My daily system is (and will continue to be) a MacBook Pro. The MacBook has sleep down pat. Close it and then open it, even 3 days later, and you're exactly where you were when you left off.
With the XPS, sometimes it sleeps and I use the fingerprint reader to get back. Sometimes it powers off and I have to power it up (and it usually, but not always) comes back to where it was.
What should I expect, and are there settings that I can update to make it more closely have the same experience as my MacBook?

I assume that in Power options, profile settings / Advanced under Sleep, you probably have the "Hibernate after" option set to a specified time. After that time, the laptop automatically wakes for an instant just to switch over to Hibernate (to avoid training the battery). So if you wake it after a longer time, it resumes from Hibernate, which takes a bit longer.
Ideally this is a good concept. Unfortunately, a few bugs may appear in this activity. Sometimes you can debug observing Event viewer / System log, but often you don't find much. If it doesn't resume you can also try using WhoCrashed to see if the crash produced any dump to debug.
I had to set Hibernate after to Never, because this function didn't work reliably and the laptop woke up and was running hot in my bag. Also if I go into Hibernate manually, it sometimes fails to recover, so I avoid using it. Sleep seems to be mostly reliable (except that it may drain the battery in a few days). A few times it also stopped waking up from Sleep, which seemed to have been somehow triggered by unsafe shutdowns, and was cured by reflashing BIOS.
