Sony 100-400 vs Tamron 150-500 for birding & travel

I currently own the excellent Sony 200-600 which I love for my birding and wildlife, but I am constantly traveling with a full kit and work gear, and it becomes hard to get into my carry on with a body, other lenses, and a computer. Its just very large. I have been thinking about adding a second telephoto to my stable for easier travel - this is based on physical size, not weight - and for the time being am considering only the 100-400 GM or the Tamron 150-500. The 70-300 options - while smaller - are not good enough, and I had and sold the Sigma 100-400, which I did not love. There is an added bonus that I love shooting macro, and each of these can close focus - albeit not macro - which my 200-600 cannot.

The 100-400 is no doubt the better lens. But it is about twice the price and 400 is not great for birding (although I do own the 1.4 TC). The 150-500 would get me there, but appears to not have the IQ or speed of the 100-400. While the 200-600 would still be my 'main' birding lens, the truth is I travel so much, I could see using this lens more by default.

Any suggestions?
