The advantage of them is they are very lightweight, and in some cases, stop non-traditional attacks (VS), and in other cases block unknown, unclassified malware, including update channel compromises (Cylance/InterceptX/Crowdstrike, etc)
Suites have more tools and technologies, but that also comes at a price of bloat, intrusiveness and heaviness. For general users, family/friends, etc. I much prefer suites. For myself, and more advanced users, I like to mix and match technology for superior protection (Anti-Exe, Lockdowns, Default Deny, SRP, AI/ML, etc).
