Denver to San Juan is 2,726 miles (4,387 km), a flight of about 4 hours 45 minutes.
The right side wins narrowly because the Front Range mountain view at takeoff is a genuinely dramatic, sustained visual moment, while the rest of the flight—flat plains, Gulf of Mexico, and open Caribbean—offers little differentiation between sides; the San Juan approach on the left is nice but brief by comparison.
Flight Path
Great Plains of Texas/Oklahoma giving way to the Gulf of Mexico, then open Caribbean Sea with no islands directly on the great-circle path until Puerto Rico comes into view.

Takeoff from DEN
RIGHTDeparting DEN on the south-facing runways, the initial climb keeps the Front Range and the snow-capped peaks near Longs Peak visible off to the west, which sits on the right side of the aircraft as it climbs south before turning east. This is the only real terrain drama on the whole route.
Landing at SIG
LEFTSIG's runway 09 approach typically comes in from the west over the island, and landing to the east puts San Juan Bay, the Isla Grande peninsula, and the Old San Juan skyline on the north side of the aircraft, which is the left side as the plane descends eastbound.
