Gutenberg is horrendous for writing long-form content. I tried to warn people before it was released in my extensive post on SmallBizTrends.
Pros:It retains the value of the original WordPress editor and dashboard
Cons:None. If you want to keep WP the way it was before Gutenberg, you need to support ClassicPress NOW so they succeed and stay around!
I installed it on my blog as soon as I discovered it.
Pros:Better performance than WordPress
Cons:A themes/plugin directory may help
ClassicPress is the base code I learned from and worked with for 10 years and I'm glad to see it continue on without drastic (destructive) changes.
Pros:Best thing since "sliced blocks" :)
Cons:None so far!
The community can decide where ClassicPress is going via a petition system. This is open source the way it should be. A stable and secure CMS with no surprises. I'm currently running about 20 sites on ClassicPress with no issues.
Pros:Friendly and supportive community. Continues the great tradition of WordPress without all the recent upheavals.
Cons:Needs more themes and plugin developers to get on board, but this is starting to happen.
I used WordPress for 10 years before deciding to move to an alternative cms. My choice is ClassicPress. I do not like the direction WordPress is taking and feel very much at home in the ClassicPress community. ClassicPress stays true to the WordPress ideals and users on my sites didn't even notice the transition. It's exactly the same as the familiar versions of WordPress up to 4.9.9. It's also easy to migrate from WordPress 5.x.
Pros:ClassicPress is like WordPress but without the writing straitjacket which is Gutenberg.
Cons:There is no better alternative to WordPress at the time of writing.
It is a WordPress done the right way. Especially it seems from the Roadmap of 2.0 version.
Pros:No childish blocks - focus on productivity, not fashion.
Cons:Short-term alternative - to use WordPress with Classic Editor. Very short-term.
ClassicPress it's community driven, so all decisions are taken in pro of the community.
Pros:It's WP without Gutenberg, almost all WordPress plugins and themes which work on wp4.9 will work on CP.
Cons:Need a own repository of themes and plugins, however anyone can use plugins and themes from the wp.org directory.
Dread filled my heart when the future of WP started filtering through and as much as I wanted to stay with WP, the introduction of Gutenberg and the forthcoming 'improvements' tied in with the total lack of empaphy from the top brass made me search for something else. Thankfully this is where ClassicPress came into play. Future projects are being slowly but surely switched over.
Pros:WP without the BS.
Cons:Needs more theme and plugin devs to come on board but, that'll come in time.
