Because everything is subjective opinions will vary but seems others like yourself who have reviewed the Conrad Las Vegas
tend to agree the beds are overly firm which is deal killer for me personally
Aria, Cosmo, Waldorf, Vdara etc and others took the middle ground right in the middle with bed firmness which I admire.
Crockfords difference in the videos I have viewed which may be misleading seems to show a plusher bed with more pillow top
padding but for all I know could be the same in feel.
It seems where Crockfords may exceed the others @ Resorts World is the higher degree of personal service (their claim not mine)
and room service to use the f&B credit with
And because of limited rooms far less crowds to contend with
Crockfords aesthetic also seems like it was somewhat more thought out by designers but also subjective to personal taste.
The bathrooms seem more attractive than Conrad as well
At the end of the day my assessment for my own personal choice would likely be save the money and points and go for the Hilton
or go all the way to Crockfords
In other words go Chevy or Cadillac but skip the Buick

Older folks may relate to that analogy

And for those who feel somewhere in the middle undecided there is always the Conrad!
Incidentally in social media the hotels still continue to fare quite poorly with some of the lowest ratings I've seen in years for new hotels.
Hopefully time will sort all that out when they get their operations fine tuned
