Unfortunately I think it is more dead than alive.
In the old days jailbreaking was done by young and wild wizzkids, most of them have now grown up and have moved on in life. Meanwhile Apple implemented more and more sophisticated hurdles.
Combine that with a very lucrative 0day market ranging from corporate to government interest.
Indeed Android is now a viable alternative to Apple, for business reasons I was forced to go to Android myself (Apple go dual-SIM!!!).
There have been some major updates without a jailbreak, let alone a new untethered (public) jailbreak.
Maybe a new one will show up after the iPhone 8 release, but chances are slim I would say.
Regarding the Android/Apple discussion, personally I still like Apple beter as it is more a mature platform whereas Android is more a teenage-like platform.
However Apple is declining. A nice article on how Apple changed:

I tend to agree, iPhone 7 did not bring anything new, Apple watch failed miserably and the last 2 Macbook refreshes where a gimmick (touchbar) and some speed enhancements which are 1 year behind on the competition.
Although I hate Microsoft, their surface book pro is a good crossover between a tablet and a PC.
Apple does not want to go to touchscreens; eats further in the iPad sales.
All in all Apple stopped designing and is now just selling, it is the death of every tech company in the long run.
