WordPress Database Clean-Up & Optimization

I am working with importing several custom post types / fields & require regular optimization (ie. selecting tables with overhead and optimizing them via phpMyAdmin currently). I would like something simple for my client to run prior to import or mass adjustment of posts. I read this article (https://premium.wpmudev.org/blog/wordpress-maintenance-101-how-to-optimize-and-repair-database-tables/) and am looking at these two plugins: http://wordpress.org/plugins/wp-optimize/ AND http://wordpress.org/plugins/wp-database-optimizer/

Has anyone had experience with these plugins? The client will be manually optimizing prior to import and I would like this to be effective and simple to use.
