Magic and cyber tackle the problem of character enhancement from 2 different angles, using 2 entirely different resources, and its important understand that.
Cyber enhancement runs on 2 resources: Essence and money. Essence is a finite resource and when its gone, its gone. Money is a flexable resource. Enhancement through ware, while depleting essence also leaves Karma available to the character to improve skills and other details, often giving a mundane character an effective "double" boost in power every time new ware AND karma are spent.
At least in the beginning as cyber has some serious caps to it. As mentioned, Essence is one such cap. The +4 augmented max is the other.
Awakened characters have a sole resource they have to manage; Karma.
Karma is used by awakened vharacters in all aspects of enhancement. Improving attributes, new skills, improving skills, new spells/powers, initiation all take Karma. Which means awakened characters improve much slower then mundane characters. And when you consider their Magic Attribute is tied to Essence, they can't "cheat" to power with cyber without taking a serious (karma) loss.
However, there is less restrictions on just how "powerful" magic can get, as the upper cap on inititation (and thus power points, magic rating) is limited only by the karma cost!

Speaking from expwrience as someone who has played the same character for 25+ years through all the edition changes: Awakened start off 'weaker' but end up extremely, game breakingly powerful. (Currently at the 10k karma mark)
