Unfortunately, its not as simple as that... its variable depending on what configuration the wick is used in, what ohm rating at the coil, what the equipment providing the power is capable of, and a variety of other factors. In my experience, mesh tends to get hotter, so more 'delicate' flavors don't always do as well with stainless mesh at the voltage/wattage I normally like. Fortunately, with the extra heat, it also produces extra vapor so dropping the power to compensate is no issue. As far as silica wicks go -- I like the flavor of them for the most part, but I seem to foul them in a couple days, tops. That alone led me towards mostly mesh.
On the other hand, I have several dripping attys that I adore -- and they all use silica wicking in the coil (albeit a very small amount)... so it really varies.
All I can say is experiment -- thats the only way you'll find what works for you... and the reality is what works for you might not be what works for me
