I disagree (there's a shock) if you getting points for something that is ultimately a positive then that's an issue.
I'm afb but I believe both sinner and erased come in 5 and 10 point varieties. Basically if your going non criminal son you get a free super advantage. At my table I'd caution Players to be mindful of this. But I tend to see disadvantages as character defining not just a path to extra points. Ymmv
However, take a look at Astral Hazing on a non-awakened character: Minor inconvenience since heal-spells are at -4 Force, but otherwise you're getting paid to be a walking Force 4 Mana Static spell.
Erased (Weekly) and SINner (regular) cancel out... but you're still spending 5 points off your cap for Positive Quality and Negative Quality points, so you're still expending resources and should get a net benefit. You can still be tracked by your SIN, and people can break into your home in the middle of the night and do bad things to you while you sleep, but Erased means that
LEGAL repercussions are going to be much easier to get rid of, if you take reasonable precautions.
Erased (Daily) and SINner cost you a net of 5 BP and take even more Quality points, so the fact that your
LEGAL troubles vanish isn't at all out of line, considering how many extra-legal threats there are. You might be teflon-coated as far as the courts are concerned, but that's not going to stop the Yakuza, or even some off-the-clock Cops, from tuning you up and leaving you in dire need of some Cyberhands if you're ever gonna use your fingers again.
SINner (Criminal) brings its own bag of pain since, until you pay Karma to get it burned for good, you still get treated like an ex-Con, with all the hassles that entails.

For some reason, I now want to play a Technomancer (non-SINner) with Alias or Idoru for a paragon, and the Erased (Daily) as a "blessing" from the Resonance Entity in question.
