A lot of the leather workers seem to use Schmetz of varying sizes.
I can only respond by suggesting a search for "sewing machine needle chart" or something similar which will give you many results including something like this

As to brand, I have no opinion, but you could try several and if you're sewing heavy material you'll want to have plenty of needles on hand anyway!
