You can likely go without augments if you're focused on shooting.
If you want to melee, you need augments. Melee, it's no contest - chrome beats adept every single time.
could you elaborate please?
This is assuming you aren't going shock gloves, shock stick, mono-whip, or
chainsaw.The big differences between the two:
Sammies have permanent stat boosts for affordable prices, higher armor/soak, and higher versatility.
Adepts have potential temporary stat boosts through Boost ____ as a simple (and you'll usually score 2 hits on average), higher initiative, higher dodge, and better specialization.
For a ranged character those are roughly about even. The adept will probably go first and has a higher chance to not get hit at all, the sammy is far better at stuff outside of combat and can take those hits and continue going. This is because guns (and the aforementioned weapons) do a set amount of damage unchanged by your stats.
Melee weapons DON'T do a set amount of damage though; they are, by and large, Strength+X. In addition, melee attacks are complex actions, not simple. This means the sammy suddenly LEAPS ahead. The ability to boost your agility as a simple action works when you can then pew pew pew as your second simple, but with a melee weapon, boosting agility means no attacking that turn, which is a major loss. On top of that, Boost Strength
does not increase your melee damage. So right off the bat, the sammy is either attacking before you, or they've got equal chance to hit since you can't activate your buff, removing your specialization bonus. Then you actually hit, and the gulf widens; the sammy can add +3 to their strength no problem, while the adept at best adds +1 from Critical Strike. To add insult to injury, this is assuming a weapon; if you're going unarmed, the sammy can either have NEW BONES or a cyberweapon of some sort to boost their unarmed strength, whereas adepts get nothing of the sort.
So, if you want to go melee, using 'ware to boost your strength and agility is near mandatory, and if you're going unarmed you THEN want more 'ware to boost your unarmed damage, and you start to wonder how much easier it would've been to just go sammy from the start.
And this is really weird and dumb, because pre-SR4, adepts
were the melee choice. Now they very distinctly play second fiddle.
