I'm going through the same dilemma of bare 100-500mm vs 100-400mm + 1.4xTC. There are those who say the TC is too detrimental. But, that's not my experience. My feelings at this stage are that the two are not so dissimilar that it makes much difference. I'll leave final judgement until either I get a 100-500mm to test directly or someone I trust does the direct comparison. Gordon Laing and dare I say him Ken Rockwell reckon if you already have the 100-400mm that there is not much reason to "upgrade" based on fairly casual comparisons.

I’ve read the same reviews and can see their point, but I like the idea of not being bound by the teleconverter in the field. I hate having to swap it in and out so much that when it’s mounted I just leave it on and when I take it off it stays in the car. Of course it can cost opportunities both ways...

The truth of the matter is that I’ll never own a big prime. I can afford whichever I want but I know I wold never use it to the point that I would “recover” the cost. I’m a walk-and-shoot photographer. I can never see myself sitting in one spot or sitting in a hide as a rule and that’s the only way I could see myself using a 500mm or 600mm. So I’m always trying to figure out the best way to extend my ‘reach’ without sacrificing complete mobility.

I’m going to buy the 100-500L and the new 1.4III. I had it on preorder at a great price and will likely be calling B&H over the next couple of days to see if the same price still holds, and if it does, I’ll go ahead with it. Then I‘ll have the best of both worlds with one set up on the R5 and the other on the EOS-R or 5D4 - the Black Rapid suspenders makes carrying both a breeze..

Here's a 1000x1000 crop from the centre this morning of a Tree Sparrow taken with the 100-400+1.4xTC on the R5. No additional sharpening, just straight out of DxO PL4 with standard settings.
