I had the 100-400 in the past but sold it to get the 300 f2.8.  The AF of the 300 f2.8 is superb.  Adding 1.4x is no issue either.  Yes, cropping is just a fact of life for BIF at 400 mm even with a cropped sensor.  The 300f2.8 plus 1.4x is very sharp even at 100 percent.

I shoot with a 5D3, have not tested how many stops the IS is useable, but don't think the TC itself affects IS other than the increased focal length.  AF is noticeable slower with the combo 300 version 1 and 2x II, so The challenge for BIF is focus more than hold ability.  Dropping to the 1.4x solves the focus issue and since you are experienced with tracking BIF with the 100-400, I think you will be amazed at the quality of the 300 v2 plus 1.4x III.  When I have a chance I will post some BIF photos with either the 1.4x or 2x.

I have the 300 f2.8 I IS and regular shoot it with a 1.4x or 2X TC hand held.  Its a bit heavy if you have to walk a couple of miles with this combo, but it is doable for me.  The attachment is a portrait of a black bear in Yellowstone at 600mm, 1/200 sec, handheld.  The iS is great.  So the answer is it depends on your level of fitness, how far you need to walk, what tele photos you have used in the past, etc. In general, you will find many people amateur like me or pros who say this lens is very handholdable.

The 1.4x III should work just fine with your 70-200 f2.8 II.   I have the 5d3 and 300 mm f2.8 and French pair it with a 1.4x II ( I hear the 1.4x III will AF faster) and love the combo.  I shoot primarily wildlife.  IQ with the 1.4x is great and AF is fast enough for birds in flight.  The 2x would slow down the AF significantly and Useable for static or slow moving animals at a distance.

I too had a100 -400 and I could get sharp pictures up to 300mm, but not at 400mm.  May be it is just me, but I traded it in for the 70-300 for a walk around teleconverter zoom and a 300 f2.8 plus 1.4x and 2x for longer focal lengths.  Just got back from 3 day at Yellowstone and these combos worked well for me.  Most of the time, I shot with the 300f2.8 and the 1.4x or 2x with images of bears, pronghorn, coyotes, birds, and a few wolves.  For closer range I used the 70-300.  The 70-300 is sharper than the 100-400 up to 300 mm and the 300mmf2.8 plus 1.4x is. Just a fantastic lens.  I could shoot handheld, from vehicle, or with a tripod for longer distance work.  Today I walked around the local park and shot a Northern Harriet at 25 yards with the 70-300 and was very pleased with it.  I had a harder time getting similar results with the 100-400 at the same distance.

I have been shooting at ISO in the 1000 - 3200 range and did not notice noise is a problem.

The Coyote photos were at ISO = 2000 and the Rabit at 100% crop was taken at ISO = 3200

I had the 100-400 and sold it to get the 300 f2.8 and the 70-300L.  The 300f2.8 is amazing and is my go to lens when I want the big gun since it takes the 1.4x and 2x well.  I'm much happier with the 70-300L as the walk around lens, lighter, sharper, smaller.  I did not get sharp pics with the 100-400 at 400mm, but it may be just me.

I wouldn't recommend the 300f2.8 as a snooping lens for taking biniki-clad women though as it is VERY obvious.  You definitely need a girl blind to conceal it ;)
