I used to use this lens when I used Canon gear and the images it produced were without exception sharp and detailed.
When I 'saw the light' and switched to Nikon gear I was given a Sigma 105mm Macro which produces equally good results, however I would not hesitate to recommend the Tamron.

I own this lens and have been using it for a couple of years. I love its sharpness and the colors are great out of this lens. I guess the only con I have seen, is that it hunts some, on autofocus, but to be honest, I do not use AF much, I use manual for macro.
I have used the AF for a few portrait shots of my hound dogs. The sharpness was amazing, the whiskers and nose textures were detailed and very pleasing to me, great dog portraits. Great color as well.
Of course I have shot flowers also with this lens, and the colors are terrific and sharpness again, superb. It is as sharp or sharper, than my Nikon 60.
One other item I sort of dislike is the push-pull of the lens, to do AF vs manual focus.
I do recommend the lens as a very sharp macro and portrait type lens.

Very sharp esp. in the center fully open, best about 5.6. Very good contrast and color rendition, nice bokeh, does an excellent job on skin tones, excellent portrait lens. Great deal for the money and an outstanding performer regardless of price.

The only real quibble I have with the Tamron, besides the aforementioned auto / manual focus clutch, is that it's not terribly accurate when focusing at a distance (~100 yards +). This really is not an issue since I rarely try to capture a long distance image with it, but it is a minor irritation which may be a product of the sample I own. All the other virtues (bokeh, sharpness, portrait use (it is NOT kind to bad skin!) have been reported accurately. Build quality is sufficient as long as you don't plan to drive nails with it.
Recommended as the one of the best values around.

The first experiences resulted in pictures with good, but not exceptional sharpness and quite some CA. So I made an Imatest resolution test at about 1:50 magnification, leading to rather disappointing values: about 1600 MTF on my D700 (the 24-70 delivers about 2000, the pre-AIS 105/ 2.5 about 2250 with that amount of sharpening I use). Correcting both CA's in NX2 brought the values up to 1800 (all value at about f 5.6 in the center; corner on the 90mm Macro only very slightly behind).
For some reasons I got the impression, that the lens is maybe optimized for the 1:1 range, and not the 1:10 situation I am often in. So I made a picture of a 8 inch ASIC wafer having about 5000 chips on it - on resolution a very demanding issue. (The wafer is coated giving some issues go get correct lightning).
Below you see the result of my experiment (800 % crop) - there are many areas where from one pixel to the other pixel more that a 50% contrast jump can be seen; indicating that at 1:1 the lens should outperform my D700. But also at 1:1 magnification CA is an issue.
I am interested to hear other experiences.

No, it does not have the build quality of a Micro-Nikkor, but it's pretty solid, produces great images, and best of all - it's a joy to use.
