Websites tell you what kind of audience their browser is aimed at. That doesn't mean it won't work for users with other tasks, but it helps to make the right choice. Developers tells which services their antidetects work best with. They all have their own algorithms for checking user data. The same browser may mask a connection by working with PayPal, but not with Facebook. Plus, each antidetect may have additional features that differentiate it from the others.
Sites provide information about how many profiles they are willing to give you for a certain amount of money. More profiles-higher price. If there is no limit on profiles, the browser may not be as convenient for all tasks. The price range is wide, but most antidetects have a free trial, so before you buy a paid version, it is better to use the browser for a few days to see if you are comfortable. If you don't have time for tests, it's worth at least watch some reviews.
What was this about...? 
I guess it was about "Lost In Translation".
Reading the post felt a bit like solving a riddle. 
Hi, Just wanted to pipe in. We have an anti-detect browser that was recently launched. It's good for affiliate marketers. You can do things like
- Social media posting from multi accounts
- Facebook ad accounts
- Outreach
We also have an affiliate program. The official launch is on 7th but there are already hundreds of users from our prelaunch.
