HK hotels are very variable. The CY HK can be had for <HK$1000. I paid that my last stay on a Saturday night a few weeks ago. The same weekend the LeM was about the same IIRC. Put some random dates into the Marriott web site and you’ll see the variance. The CY HK has been HK$2000 some weekends when the Marriott OP was <HK$1500. All prices quoted inc taxes etc.

In KL if you have status then the best value for cash is probably LeM because of its excellent lounge and for points the Sheraton because it’s a lower category. The Ren has its fans and all three are probably interchangeable. The cheaper brands aren’t that much cheaper for cash but don’t have lounges. The Aloft for example is frequently the same cash price as the nearby LeM but LeM is much better if you’ve got status and lounge access. You don’t need hotels from the Westin upwards if it’s a mattress run and you don’t feel you need to be directly on Bukit Bintang.
