Adepts, Mages and Shamans, Which is better for a beginner? Options

[Mana Child]

Ive been wondering cuase lately ive been getting alittle practise making characters and passing them around to a few friends i have on the forums to see how they are.
And i was wondering:
What is easier to play?
An adept, a mage or a shaman?

Could anyone tell me.
Also what are some situations where somthing like killing hands is useful and can you use it for astral combat (i'm sure adepts can do astral combat)
Is it possible to use adept abitlities to effectivly augment abilities to make a gunbunny type character thats almost or just as good as a cybered up one?

if ive said somthing wrong here please be nice as there may be a few things that i dont know what i'm talking about.
