With all things considered the UAE is safer than︁ most banana republic tax havens, Malta or Cyprus when it comes to banking. The only︂ real issue is that the regulatory landscape can change very rapidly and affect your compliance/tax︃ implications. Democracy wise well, i couldn't give a rats a*s if it's a dictatorship so︄ long as the business climate is friendly enough and the banks are reliable. Don't commit︅ crimes and don't try to launder cash through UAE entities and you won't have to︆ worry about the government going dictatorship mode on you.
I dealt with many jurisdictions before,︇ never had a single issue with UAE banks other than maybe cryptocurrency-related deposits. It's hit︈ or miss depending on the bank. About the costs, if people are concerned about that︉ (to a reasonable extent), they don't need an offshore setup to begin with.
