Delta Comfort+ or Premium Select for a long flight to Europe?

For an overnight flight, I’d lean towards Premium Select:

• Seat: wider, with more recline plus a leg rest and footrest, so sleeping is easier.
• Service: better meals, drinks and an amenity kit on many long-haul flights.
• Cabin: smaller and quieter than the main economy cabin.

Comfort+ is still a solid upgrade, mainly for extra legroom, but it is the same economy seat. For long flights the gap is noticeable. Here is a clear Delta Comfort+ vs Premium Select comparison that helped me decide.
