I like my Tammy a lot. Only comment I can make is the newer ones seem to have better Quality control than the ealier ones and that is only heresay. Anything else can be found here in the lens review section.

I used the Tammy until recently (nearly three years) when I changed to a Pentx DA 70-300mm.

I'm sorry I did not get the Pentx in the first place.

The purple fringing on the Tammy is excessive and spoils many shots - it is sharp for sure but has less contrast than the Pentax and the colour is slightly less pronounced than on the Pentax. Using Chromatic Aberration reduction software damages the original colours in the pix as well, especially on fine details and one loses colour contrast in the effort to control the PF.

Sometimes there has also been green fringing with the Tammy, which software cannot handle anyway.

So my advice is, save up a bit longer and get the Pentax lens instead, it really is that much better and very satisfying to use because of that fact.

If you are hooked on getting the Tammy, then at least you have access to the Pentax raw softare that comes with your camera - in that software, you can reduce specific colours and reduce the impact of the purple fringing.

I have not had the Tamron, but would consider trying one. My understanding is that the PF is more worse at longer lengths, so it might depend partly on how you plan to use the lens.

I did own the DA 55-300 briefly, but my copy significantly underperformed both my old 100-300F and my DA 50-200. I had hoped to replace both lenses with the 55-300. I sent it back for no cost to me, and that's a very important possibility to consider, no matter what lens you buy. You have to be able to return it if it's defective (or even if you just don't like it.)
