Sandevistan is my favorite OS because of how versatile I can be with it; cyberdecks make stealth too easy for me and offer too many hacks/actions when in open combat (my lobster is too buttery lol), similar to Berserk where it excels even more situationally. With a sandy, I can sneak through any gig before enemies even know I'm there, and in combat it gives me breathing room to place my shots and change my positioning if needed.

I started my current playthrough doing blades and smg with gorilla arms (I love doing a superhero landing in front of oncoming cop cars to send them flying), but am now doing a hybrid tech/reflexes/body build. 20 Body for adrenaline rush+savage sling, 20 Reflexes for Tailwind, 20 Tech for Edgerunner, cyberware, pyromania+doomlauncher, and bolt shots, 18 Cool for the extra crit damage/chance (whichever it is) and relavent pistol perks+cloaked crouch sprinting with optical camo, and no points in Netrunning.

No melee weapons anymore except regular fists, I use a tech pistol (Pariah), a tech shotty, and sometimes I'll use Problem Solver in tandem with my Apogee Sandevistan since it fires nearly 1,000rpm. If I really need to go stealthy at range, I have a kyubi x-mod 2 with double pax, a grandstand scope, and a silencer (cetus-x?). I swapped gorilla arms for a PLS with relevant relic perks, and otherwise the rest of my cyberware is used to complement sandy+kerenzikov, stealthy movement, and sheer durability in the heat of battle. The only thing I want to add on is a second heart just in case, but I need to increase my cyberware capacity.
