Depends, low hanging fruit where you want to scrape things and need automation, Gologin cloud browsers. Not the best fingerprints, way back as far chromium versions go, but does the job.
Harder website, automation or not, Multilogin, they seem to have a downtime here and there, but doing things via API is rock solid, easily best fingerprint and canvas integrity, I would like to add Linkensphere here but their admins are more rude than me(just kidding I dont care) , but they have some catastrophic and very dangerous default settings and off all the features they have, you need to find out which are the good ones, theyre scattered between payment tiers and if you check their chat groups, youll see they have proxy integration downtimes recently , so yeah, not beginner friendly.
For the one level further up than that, youll need some pre 2020 mac devices or windows hosting, a server with gpu. The second one requires programming knowledge thats not trivial, as in Windows erver maintenance and an orchestrator in a back end language where a scripting language often wont do the trick.
The most sophisticated setups you need vectort13 , that is not an anti detect, thats a thing that spawns real windows machines from a VB env, not VM, forget vm. This is costly, the guide to set up one instance video is over 60 minutes(but good 60 minutes) and eventually this requires some strong hosting too.
Essentially, layer 7 anti detects can only do so much, they manipulate JS properties at the browser layer and that comes with systemic limitation. I do not want to call it playing with barbies in a sandbox, but you will not be sailing through cashiers and platform like ebay with that.
All this is before speaking of proxies and DNS, which is a whole other matter, but just as important.
