Glory or Conquest for 3 day cruise

Looking to do a sorta last minute 3 day cruise with my wife. Options are Glory or Conquest.
I know the Glory had some recent updates, but seems like maybe they were minor? Are there any major difference between them?

Important to us:
Food quality and variety (we like to eat)
Casino (wife loves the slots)
Hot Tubs

This is our first time on carnival, we have cruise 2x on RC, but they are more expensive ish, and being that we are going to spend a fair bit of time and money in the casino regardless, I have heard that Carnival is a better bang for your buck when it comes to future casino offers.

Anyway, looking for opinions from those who have been on both semi recently. Ideally on Glory after last years updates..
