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.

We use the 70-200 F4 MK I with IS and with a 1.4x

We have recently added the 70-200 2.8 mkii which will likely replace the above.

We also use the 100-400 mkii with a 1.4x. they are quite different systems for different jobs.

I'm not sure which F4 your using.
