from the lenses i ve tried, i ve seen macro lenses have creamy bokeh in macro range. but in normal focus range other primes are better. they also have long focus throw in macro range but not in normal use
they are bigger, slower, and a burden to use compared to normal lenses. only macro lens i like using in normal situations was canon 100mm usm macro, and the reason was only its mechanical build which doesnt require lens to extend for closer focus
i tried pentax 100, 50 macro , pentax 77 ltd, 40 ltd and jupiter 85, pentax m 50 f1.7 . and i can say if u are not taking macro or close ups carrying a macro lens is not necessary for sharpness, bokeh or anything u can think of
ah and they are also so big u cant properly use with internal flash of camera '-.-
