This is the one I had been looking at before the DeWalt:

And here it is on Amazon:

The reviews don't look very good compared to the DeWalt.
Needless to say I'm iffy after reading a lot of the reviews, particularly on the Home Depot website.
The one you linked to has good reviews, but that's for 15 gauge nails, which seem maybe a bit too much for finishing trim, no?
You tell me? Given the choice between 15, 16, and 18 gauge nails, which ones would be ideal for installing doors, door trim, base molding, window trim, etc.?
Agreed, that 18 gauge gun gets 3 star reviews all over the place. Most common complaint is that the gun does not sink the nails enough and leaves them level with the trim.
Unfortuately I cannot advise what gauge nail you should use, it appears 18 gauge is the way to go, but I am no expert . Nor do I know if these complaints are caused by rookie mistakes.
Based on the reviews I probably would not buy this gun, but since I have a few M18 tools I would buy it, carefully test out a few nails, and if it did not work neatly place in box and return. If you do not have other M18 tools them I would go for that Dewalt, Makita or Bosch...the standard big box store brands.
