Los has been a really interesting experience so far. In all the games I played with him so far, the corp paused when I ran on the first ice each turn. "Do I rez this now? It's 2cr for him" Especially so, if it was an ETR-ice. Also I find him actually more consistent than Gabe for firing at least 3 times per game, because the corp will rez ice at least on the centrals whereas Gabe can get locked out of HQ in the mid to late game.
When you choose Los you most likely will run cards that can derez such as Emergency Shutdown or Crescentus. Los is also the only contender for using Exploit which can be quite a tempo swing of you paying 2cr and the corp losing about 10-12cr. For the latter to fire you only need an additional Archives run, as you usually would like to run R&D and HQ anyways.
I also had some success including Ice Analyzer and Compromised Employee for additional value and some of the bird breakers. As of yet, with only Station One out, he really lacks a signature console, so I have tried using Reflection, as jacking out after the first ice may help you maximize his ability.
