Starting a new game which edition, Sell me on an edition Options

[Tyrrell]

I played a great deal of first edition back in the day. I collected a fair amount of third edition, and I played perhaps a dozen sessions of fourth edition several years back.

I've never had any problem with games being too complex, only games being poorly thought out. Simplicity didn't stop Eldrich Ass Kicking from being an incredibly poorly designed game and complexity didn't stop Ars Magica 5th edition from being incredibly amazing. I tell you this because I have some months of open space on my gaming Calander, and I am looking at game mastering some Shadowrun. Since I've played, there have been two new editions. I've read some poor reviews of sixth edition but many of the poor reviews say "it's too complex" which is, in my experience, rarely a criticism that turns out to be true.

Would anyone care to give me feedback on the two new editions, or if it's what you believe, feel free to make an argument for one of the three editions that I already have.

Are there strong feelings? Are there clear differences I should know about?
