The suffix "Smart Security" or "Internet Security" is a synonim for: I'm doing great alone!

Try not to add anything over it. All I would pair a suite with are complements like OSArmor or Hard_Configurator.
You are correct my friend. Good security suites like Kaspersky and ESET are enough alone when combined with common sense. I don't use OSA since I have SysHardener. I instead bought AdGuard lifetime licence since it was at 50% discount.
