I've been using Divi builder for a number of years, having opted for lifetime access when I was deciding between this and a competitor Wordpress builder. It feels like I made the right choice - I've since also moved hosting providers based on their recommendation which has resulted in further improvements in load speed and Google Core Web Vitals :) Quite honestly I've never used the website packs (opting for building unique themes based around the default Divi theme) however for builds from scratch (using Divi Theme as the parent theme), it's generally decreased implementation time by around 60-70% which in itself provides a great time and cost saving. Support is timely (responses usually within an hour or so via Live Chat and/or email despite me being a different timezone) whilst they've never fobbed me off by pointing me in the direction of a support post (as most customer support teams do) - instead, they're always seemingly happy to discuss the issue (with me it's usually quite technical) and provide a solution. A recent issue with viewing tablet/mobile in the visual builder view was actually a result of custom code in my custom theme, but this didn't stop them providing a solution. They do notably release regular improvements and fixes, with my only frustration at this point relating to a rather long timescale for fixing for a custom post bug however I've no doubt this will be resolved before too long! All in all it's a great Wordpress builder and there is nothing that would make me move over to an alternate builder. Definitely worth the $199 lifetime access!
