In Europe you certainly do need a longer focal length.I've put some serious thought to doing that. During my first few months with the 300, my summer subjects suited the lens perfectly. I literally didn't touch the 600 for 2-3 months. If those type of summer conditions and subjects were the norm year round I'd sell the 600. But I told myself I was probably getting ahead of myself and would need to go through the winter first to see if the 600GM creeped back out of the closet. Well it certainly has, been using it more 50/50 with the 300GM. That is mostly due to the light levels and somewhat due to the subjects.
So everyone will need to make such a decision on their own based on their own subjects, light levels and tolerance for the heavier lens. Do you need f/4 at 600mm? Do you need 840mm or even 1200mm?
There is no doubt I much more enjoy being out shooting with the lighter/smaller 300GM. Just like I've always enjoyed my smaller lenses over the years like EF300II, EF400DOII, 500PF, Z400/4.5.
I've never been a huge fan of TCs on the other Sony lenses. The only lens I'd been happy with the 2xTC was the 70-200II (borrowed briefly from a friend). The 300GM is the only other lens that it works well on. It is terrible on the 400GM and mediocre on the 600GM (IMO, YMMV).
So I'm keeping the 600GM. But I can certainly see people being very happy just using the 300GM and TCs.
And to my suprise I find 2x TC work really well with 600. And I am picky with sharpness. For instance I have never accepted 1.4 on 200-600 - mounted on a9. To my suprise if light is good (so not really low but also not super bright, as I also do not accept shadows in pictures) the 600 with 2x TC works really well.
