Salient has the most beautifully customized backend visual composer page builder on the market.
It speeds up development big time, is well organized and the latest update (12.x) just added to it.
Sadly there have been a couple of minor bugs in the theme for a long time now.
They could also improve their performance features regarding page builder code/files loaded in frontend and include their lazy loading for all there page builder elements that have images. Some other themes like Impreza got an edge here over salient.
Despite its flaws, I still give it 5 stars, and I have used a lot, really a lot, Wordpress themes in my life.
Salient is my go-to theme for small projects for a very long time now.
It's just sometimes a love-hate relationship when a minor bug shows again, or when I am missing a comfort feature that I have in other themes.
