Not a Centurion cardholder, but I have a couple of comments on the EVA Platinum:
- The miles earning rate is *not* great. 1 mile per $25 is pretty low, even by Taiwan standards. You can do the same or better with other cards with zero or low annual fees. There are a bunch of blogs covering this but here's just one example: https://blog.tripplus.cc/zh/148282/b...iles_in_taiwan
- You get a bonus for overseas spending, but you pay a 2% foreign exchange fee. Most Taiwan cards only charge 1.5%.
- The upgrade vouchers do boost the earning a good amount, at least for the required spend. But the upgrade vouchers can be difficult to use, because they are only valuable for long-haul flights. Also they expire within a year, and you need to fly (not just book) before they expire.
- The hotel gym perk is limited to 4 times a month, and it needs to be reserved in advance. I assume llary is able to make good use of it because he is based in Taichung. Most cardholders are in Taipei and it is incredibly tedious to get a reservation there.
- EVA Platinum gets the same priority check-in / lounge benefit as the Cathay premium card. So it's a bit of a wasted benefit to have both.
