One possible comparison might look like this:
Divi for WP is currently priced at about £65 per year (or £180 for lifetime). What does that get you?
A really cohesive, smooth and consistent experience for visually laying out and building your site on top of WP. No issues with incompatibilities, inconsistent styling, publishing challenges or anything like that.
You get 100+ site templates; most of them are actually really good and are already categorised by use-case. Being built on WP and with special building blocks for blogs, you are surely covered for blogs. There is a really good form plugin which comes with Divi too - so in most cases you can set up and get your form working easily and completely consistently with the rest of the design experience.
You get the Extra theme, the Bloom email optin plugin and the Monarch social media plugin. There is a proper marketplace, a facebook group and virtual meetups.
If you want to sell, there are lots of options: Divi comes with WooCommerce helper modules ready to go. If you want a login system, then that’s easy - Divi comes with a login module too.
Its easy to backup your pages and re-using layouts is super easy. You can also leverage hundreds of other WP plugins - many of which are free.
The possible weakness is security - but I think this is improving. Free plugins like loginizer, cerber and login lockdown are effective. Making sure you follow best practices do help mitigate risk.
What might an equivalent set up look like using RW?
RW Core: £90
Stacks 4: £43
Total: £263 (approx).
If you want to offer logins, sell or get a template to get you kick started - you will need other add-ons too which take you off into more cost and into separate experiences where the cohesiveness and consistency breaks apart.
Is this an unjust comparison? Would seriously like to know (before this thread gets closed).
