This year I discovered the EF 2x II is much better than the EF 2x, and that the EF 1.4x III is much better than the EF 1.4x.

I have stopped using the Kenko DG 1.4x as much as possible, since it is inferior to even the EF 1.4x.

All tested with the original 300/2.8 L and 5DSR.

ALL teleconverted lenses should be closed one additional stop to maximize sharpness.

Good general rule with most lenses - although I think the very best are absolutely fine wide open with 1.4X TC even on 32 MP APSC.  However the OP’s proposed combo does need stopping down

My general experience is that a 2x is worthwhile over 1.4x, but even the L zooms don't take all that well with teleconverters. Maybe start with the 1.4x and cropping like someone else said.
