Like others have said, the rules are... bad. Especially the latest edition. A couple of the older editions are "favorites," but still mixed bags, and lots of people just take the setting and use it in another system entirely.

There's a Shadowrun actual play podcast called NeoScum that I loved (now concluded), and it began with "It's like D&D mixed with Bladerunner!" and ended with "Fuck this, fuck Shadowrun, the universe rearranges itself so we can play a different game." They even had a goofy recurring bit they would do whenever they had to stop play to look up rules or calculate something, which happened constantly. It's also not a player issue, since they've switched to Call of Cthulhu for another story (Gutter) and just don't have that problem.

Look at older editions. 6th is hot garbage published with criminally low quality material and he didn't pay the freelance writers that contributed to the game.

Hong Kong is exceptionally wordy. That's not necessarily bad, but I spent far more time going through conversations with the party than I did on runs, and I'm a quick reader. They're excellently written characters, but the conversations had little interactivity and were just pages of text with ocassional dialogue options. Conversation in Dragonfall flowed much better.

Gobbet is still the best character, though.

Still trying to dig through Returns myself, I heard latter two games are even better.

Others have given alternatives, but no one has offered Savage Worlds. It'd probably work great in a cyberpunk setting with magic, and it plays super easy.

You could just run it straight out of the box with the SWADE rulebook, but there're published books (and free homebrews) that go for that feeling as well (like Sprawlrunners).

I can't comment on Into The Odd, but I would consider either The Sprawl or Runners In The Shadows. The former is a general purpose cyberpunk system built on Apocalypse World and the latter is a Shadowrun hack of Blades in the Dark.

And I guess I'd be remiss if I didn't also mention that I've built my own system for my Shadowrun campaigns, called Straylight. I'm in private playtesting right now, and I plan to have the first public playtest draft up very shortly (weeks or days, depending on how things go).

Try Cities Without Number! It's also an OSR game, and is more well-suited for the Sixth World setting.

Don't know anything about Into the Odd, but I know Blades in the Dark had some people working on a Shadowrun conversion; the heist nature of that game appealed to them. GURPS also handles Shadowrun pretty easily, you can find other people's conversions online.

Shadowrun: Anarchy is rules lite. Apparently a new version is coming this year.

Shadowrun: Anarchy was a rules lite version of Shadowrun. I had to search the name to remember it and apparently 2.0 is kickstarting this year.
