Good optimization works hand in hand with a character concept. If Shadowrun min/maxing was purely about "The Best" character they'd be Mages and Mystic Adepts exclusively.
Some choices are simply mechanically supporting being good at something that have nothing to do with the character concept. Can you really RP the difference between Firearms 6 and Firearms 4?
Other choices, like what kind of sword do I swing, are assumptions you build around.
I've built Hobbes in 4 out of 5 editions (Skipped 4th, 6th is pending) and she's always been Human, Samurai, former CAS Marine Force Recon, hated Aztek. The rest is whatever the most effective combat machine I can squeeze out of any particular edition given those parameters. Will be again in 6th.
