Another factor is weather and what the cloud coverage is like. That can ruin any good views even if the runway in use would ordinarily lend itself to good views.
The only time where I deliberately picked to sit on a certain side of an aircraft was St Lucia so I could see the Pitons from the air. Most of the time you will land from the west, so give TATL flights reach St Lucia from the north and skirt the western side of the island before landing in the south, you're guaranteed good views of the Pitons and the island in general if you sit on the left-hand side, they're taking off and landing in an easterly direction and there's no low clouds.
