DNS Applications vs Private DNS (lemmy.ca)

Am always confused about use an app like rethinkdns, invizible pro, adguard, etc. to manage dns requests on my phone or just use the private dns ?

Is there any privacy advantage or security concern over them ? When i use an app, all dns queries can be routed through my preffered dns (like in a bloated phone all tracking requests can be blocked) ? Private dns is easy for the system to bypass ?

I always use rethinkdns and block bypassed dns, so i think now every dns is routed through rethinkdns and its impossible to cause a leak. Is that a myth as no dns app can provide that much privacy or security ?

How effective is an application firewall than a network level firewall like nextdns ?

Allover question is, may i use a application firewall or network level firewall ?

As best I understand it, running a private caching DNS server is the only guaranteed increase in privacy for DNS. That server still has to reach out to the net the first time a request is made, but will resolve all subsequent requests locally. DNSSEC to a privacy respecting DNS provider like quad9 at 149.112.112.112 from your local DNS server. Mayhaps the best you could do for a roaming device like a phone is to run a decent VPN with an option to prevent DNS leaks.
