They handle browser fingerprinting differently and each has its own approach to profile management. Multilogin has been around longer so it's more established, but that also means it costs significantly more. GoLogin is newer and cheaper, though some advanced users say the fingerprint quality isn't quite the same level. Really depends on what you're doing with it and how much you're willing to spend monthly. For casual use the cheaper option works fine, for serious operations you might want the premium one.
