Vegas night out: Kaskade vs. The Chainsmokers vs. Zedd

Ill be in Vegas next weekend (Jan 10). Looking to get advice on what nightclub event to go to - considering artist, venue, expected crowd/vibe:

• Kaskade @ Zouk - this is the official CES afterparty (if that matters)
• The Chainsmokers @ XS
• Zedd @ Omnia

Im generally new to EDM - I know Kaskade is a big deal, but being open-minded. I consider Kaskade pure house.

The Chainsmokers feel like they go a bit a harder than Kaskade (more dubstep, breakbeat)

Zedd sounds very pop-y in terms of his mixes (not my preference, but more accessible for my wife who's not a huge EDM fan).

I just listened to some sets for a bit, but would appreciate your thoughts!
