I tested TC's with a Tamron 150-600 mm a while ago and found that a comparable crop was better than a full frame shot with a TC. For birding and nature work I use a Nikon D5300 which has 25mp and no aliasing filters for 225-900mm eq. As a bonus it has a built in GPS, unlike the D850 which requires a dangle.
Dangle ??
That answers the question that Eric has been asking for a while.
DX using ccd derived x1.5 is better than FX with TCx1.4.
Logically 20-24MP DX is equivalent to 40-45MP FX. But there is a potential difference due to S/N on smaller photosites.
