Questions on how to best set up NextDNS: Yogadns, NextDNS, Manual config are ALL recommended!

I pay for NextDNS. I use blocklists "OISD" and HaGeZi Multi Pro.

There seems to be 4 ways to set it up:

1. Manual over HTTPS "recommended"

2. NextDNS App ("recommended" by NextDNS wiki)

3. Manual with IPV6 (says "or" recommended if device supports IPv6 (mine does).

4. YogaDNS. "advanced"

CAN someone please explain the pros and cons of each method? For instance WHY on earth would NextDNS recommend another DNS tool like YogaDNS, is this not a conflict of interest?

I just do not understand why NextDNS does not explain this more themselves and it says "recommended" on basically every method. It is really confusing and NOT helpful to a new user new to this stuff.
