I don't use either, but expect the RF 100-400 to be more versatile and deliver better IQ than the 70-200 f/4 plus 2x converter, so I would take the RF over the TC combi. Best possible IQ is the 70-200 plus the 400mm prime. The latter is a full stop faster and (by far) the sharpest option.

Edit : the RF has IS, which helps a lot a lower f-ratios.

Sandor.

I don't think it's a foregone conclusion that the 70-200 plus TC is worse. Looking at The Digital Picture's crops, the V2 f/4.0 with the TC is very comparable, if not better. Feel free to check for yourself, Crops.

But here is a low-res snippet:

RF 100-400 on top and 70-200 II f4.0 + 2x on the bottom.

That said, I'd by the native lens over a new TC for the EF body as I too would assume everything else would be better without going through the TC.

I compared the original 70-200 f/4 , which is the one the OP has in the gear list. That still is a fine lens, but less so when used with a 2x TC. The version II does a lot better and is no compare.
