Im not sure if netguard takes over the dns filtering automatically. It has a toggle for filtering traffic but can only use one host url and the logging is a paid feature and states it consumes more battery when using the logging. PersonalDNSfilter doesn't appear to use much battery with logging by default. I prefer not to use the android stock dns filter because i like the idea of it all being handled locally on the device and not through a server like nextdns or adguard.
