I like the standard LOWI. The airport is regularly updated, and well maintained. Along with good traffic from both General Aviation to A320’s and 737’s. Innsbruck is featured in a few apps and games, along with it’s beautiful mountain views, and the arrival procedures are amazing!
I have to also go with these because I’m biased:
CYVR - Vancouver’s runway 8 approaches are stunning! Amazing approach over the ocean, with the city ahead and untouched mountains on the left!
EGKK - my home International airport. Gatwick is pretty fun to arrive with the arrival procedures. It gives great views of the south coast and my home town.
EGMD - Who doesn’t like their home airport? I’ve flow here a lot irl, so I love it!
