I shoot the Sony 24-105mm regularly. I very briefly tested the Tamron 28-75mm that my local store had in stock.
I am very impressed with the 28-75. It is well built, has some unique features, and is optically excellent for a zoom. Yes, a slight bit sharper in the corners than the Sony. I was very tempted to switch to it. It would complete the Tamron f/2.8 Zoom trilogy for me. I already have and am pleased with the 17-28, and the 70-180. That would be an excellent and capable travel kit. However, for now I have decided to stick with the Sony 24-105.
Midrange zooms like this I use as much for a walk around, as I do for landscapes. In this capacity I find that the expanded focal lengths the Sony provides very valuable. I would miss that.
In its capacity as a hand held walkaround lens the built in image stabilization is a big plus. In low light situations it more than compensates for being one stop slower. I will get more keepers using it.
Stopped down to landscape apertures and shot on a tripod both lenses have excellent IQ. I don't think there will be any significant difference after post processing. I do think that at the stopped down apertures for quick landscapes hand held, the image stabilization will get me more sharp images.
At times I would prefer the f/2.8 aperture of the Tamron for subject separation. But I find I am able to get what I need at f/4 with positioning, FL, and other techniques.
The 24-105 pairs better with some lens selections when going to places where longer FL are an advantage. When I am going to take my 100-400 (+TC) instead of the 70-180 on a trip that includes long landscapes, or wildlife opportunities, the 24-105 provides seamless focal length continuity.
I hope you find this brief discussion on why I made my choice useful.
