After having played with WordPress for several months now, it's about time to compare it to QuickerSite. Or better, ask myself the question: when to use WordPress and when to stick with QuickerSite?

When stick with QS?

• For small sites
  
  QS has a 14MB codebase. WordPress starts with a 80MB codebase and a 10MB MySQL database. The WordPress codebase quickly grows into 100's of megabytes in case you use plugins. If you host 100's of such websites, WordPress blows up your server's hard disk.
   
• For customers who do not want to dive into the complexity of the WP admin panel
  
  Let's face this. The WP-way of dealing with content is complex. Posts, pages, blocks, patterns, templates, plugins, themes, but above all: the way all these are all mixed up. An average non-tech user is not able to use WordPress without at least one or two training sessions. As a self-employed entrepeneur, you may find yourself in a position where you simply cannot provide adequate support for a large WordPress user/customerbase.
   
• For speed, performance and security-reasons
   
  QS development has ended years ago but it's still rocking fast, solid and safe. WP development is always ongoing and you never know when security/performance bugs will hit your site. 
   
• If you are into Classic ASP development, QS is your perfect partner.
   
• In case you need an intranet with dozens (or even hundreds) of site editors, each having access to their own pages and media (only)
   
• If you know how to deal with HTML, CSS and JavaScript, you may find QS somewhat easier to integrate with them.

When use WP?

• If you need e-commerce (Woocommerce is a great, no, it's an AMAZING plugin)
• For complex websites with lots of different functionality, you need lots of plugins for
• If you are into PHP development, WP is a no-brainer.
• If your customer is willing to learn and dive into the complexity of the WP admin panel, go for it.

In all honesty, I prefer to keep on using QS for most sites I ever built and ever will build or need. Except in case I'd need e-commerce. I really fell in love with Woocommerce, even though it messes up the performance of your complete site. Even then... love it. But not enough to use WP for any type of site. WP is simply too bloated.
