My verdict: the veteran that has been surpassed.
PhantomBuster remains useful for quick tinkering, but it's no longer the reference it was. It's clearly 'old tech' now. I don't really use it anymore, there are plenty of better options today. It's still acceptable for 'tinkering' with LinkedIn cheaply and easily if you just want a quick script without coding, but it's no longer the reference.
What I like less: the tool hasn't evolved much in years. LinkedIn bans are frequent if you're not careful with limits. And for serious and high-volume scraping, other solutions are clearly more robust and reliable.
My advice: use PhantomBuster for quick tests or prototyping. For serious and high-volume LinkedIn scraping, look at Evaboot, Captain Data, or build something custom with Apify. And watch out for LinkedIn limits to avoid bans.
