I think I remember a developer mentioning, that in the upcoming, now current version of Shadowrun, there should have been a greater distinction between the different traditions.
Drain resistance attribute is a factor, but in my opinion not that big a deal. I do hope, that in the inevitably upcoming magic splatbook, there will be options for greater distinction between the hermetic, shamanistic and other upcoming traditions. Logic is quite important for next to all technical and medical skills, as well as mental limit and knowledge skills. Charisma is very important for all social skills, social limit and contacts.
As elves get a rather substantial +2 bonus to charisma, a lot of players prefer to create shamanistic elves. On the other hand, no race gains a bonus to logic, but that attribute is augmentable via bioware implant, if you choose to take a hit in essence and correspondingly magic rating.
Ultimately it boils down to how you imagine your character and how you want to play him/her. Charming and Intuitive for whom magic is a religious experience, or as a determined logician that calculates magic in rigid formulas and eqations. Its a decision that is as fundamental as gender or race, maybe even moreso.
