Its important to note that the game gives you so many points, you will likely have most of the augs by the time you finish the game regardless.
With that in mind, stealthy characters will benifit most from the hacking capture and hacking stealth augs, Icarus landing, lift heavy objects and improved jump height (they allow you to reach locations that you would not otherwise be able to reach and open some new paths).
Improving the radar so enemies don't get the jump on you, and the double takedown also help in my opinion. The two guards must be close together, and you will notice the takedown icon will change, showing you can hit 2 opponents. It is very useful as many parts of the game have several guards very close together or moving in teams, and the ability to down 2 at once, silently, is very useful. Also - in a bizzare decision, you can't seem to use double take down if the guards are at different heights -- if one is standing and one sitting, you have to get them seperately.
If you are stealthy but lethal, punch through walls is good, otherwise it is only good for looting some extra goodies in some spots. If you use scoped weapons a lot, the aim stabilizer will help with your scope sway making longer shots much easier - especially important for tranq gun users where head shots are vital in a crowded room.
I also recomend increased invintory space (more stuff to carry means more options on how to deal with guards), cloak (useful in some rooms where it is hard to stay out of sight), and run silent. All have limited uses, but you will probably be thankful you purchased them at at least one point in the game.
Once all that is handled, the Casie mind-reading aug, and vision upgrades can be useful in select scenarios.
Everything else... use your best judgement .
PS - the typhoon is the ultimate "I screwed up and now have to kill a whole room of guys but haven't been investing in combat gear" aug. If you are stealthy and reload a save after getting spotted -- don't bother. If you are the type that doesn't load a save even after they have been spotted and everything goes to hell, the typhoon will save your ass in the late-game. Don't worry about the second boss.
