Here is the current best runner deck in my group. Even though all 3 runners decks are 'playable' the Criminal one felt it had the most bang for the buck in faction. Stats from the free online platform seems to confirm that across these games, criminals are winning about 60% of the time, ahead of the other runner factions. Here is our take on it (was unable to paste the linkable version, going with text version):

I think criminal is the best at forcing the corp to spread out. Meaning it has to defend multiple servers early. They have to defene HQ (identity power, account siphon), they have to defend archive (sneakdoor), they have to defense R&D (in general but also especially with maker's eye). They also have to defend their remote servers (PAD) or simply risk 'giving' bank jobs too easily. Basically they have to defend everywhere which force them to run thinner.
On top of that, criminals, through identity power, desperado, account siphon, bank jobs, etc, generate the most revenue currently. Inside job is also not to be underated and help the runner 'save' bits while being 'tech' allowing to skip some bad stuff.
Criminals have the worse icebreakers, something that could in theory be a problem but they also have special order which patch that hole nicely with a few out of faction breakers.
Lastly they have tools that fit in the current meta (femme fatale for tollbooth, decoy and crash space for tag and bag, etc).
Give it a try and let me know what you think.
