Is Kuala Lumpur more hygienic? You bet. Is there more 'order'? For sure.
Guess what! Kuala Lumpur is not in my top 10. Maybe not even top 20.
If I want order and hygiene, I go to Singapore, which is tied for the top spot on my favourite city list.
Bangkok is so charming because... it's Bangkok. Change that drastically (for example by imposing 'order and hygiene') and you get something like a watered down Kuala Lumpur.
Thanks, but no thanks.
