Well it depends a bit, Its true that throwing now does a little bit less damage than before (now archery and throwing do the same), but if you ask about which skill to use, depends on how do you want to play. Each skill have pros and cons :
For throwing : You need to find the sweet position for doing the max damage, now garg have 45hci and not 50, you can use a shield too, easier to make suits for a thrower ( you save a lot of mods because of the default high resists on garg armors, so you can use other mods instead), but you cant max the lmc inherit bonus, and you can use pots if you dont use shield.
For archery : You always do max damage at any distance, as an elf you can use woodland armor, can max the inherit lmc bonus, all weapons are 2h (need balanced for pots), as an elf you have 20 extra mana, you can use more artifacts and high end items than a garg can use, you need arrows or bolts.
I particullary prefer archery because of the +20 mana being an elf, max the inherit lmc bonus and can do max damage at any distance, but as i said, it depends on how you like to play.
