I would say it depends on your use case and where you use it.
If you have the budget and want the gear range, reliability, and ease of maintenance. Also if you are using in hilly areas with a mid drive motor and big loads I’d say it’s even more reason to get it. It’s a sick hub but very expensive.

I've used both quite a lot and the Rohloff is definitely better. Having said that, I probably wouldn't spend my own money on one. I never had a failure on the Alfine that made the bike anywhere close to unrideable, although my knees were quite regularly bruised from having the gears slip when I was out of the saddle, banging in to any manner of oddly shaped angles on the cockpit of a Bullitt. An Alfine needs more looking after than a Rohloff and won't give you the same range of gears or ride as nicely but is pretty much fine.
Is the jump from alfine to Rohloff worth it? Does it really change the experience?
