Which caribbean liveaboard for January

[catskill diver]

Looking for opinions on which liveaboard for late December or early January. My wife's 50th b-day and would be her 100th dive.
Its narrowed down to T and C or Belize for several reasons but which one and why ?
Is the weather / water temp or viz going to be any different from one to another. I've already read about the chefs and crews from aggressor and explorer.
I'm sure they are both outstanding - anything else to add.. ease of arrival and departures etc
Thx Cat

I think that the water would be warmer in Belize in January so that might be an issue to consider.

If it comes down to Chefs go Explorer. I think the waters would be calmer and warmer in Belize.
