I never tried Semplice and I'm sure it depends on what you're trying to achieve, but my clients are always happier with a custom theme with clean custom drag-and-drop elements (usually with Unyson or Visual Composer). It never gave me any issues with SEO, minification, or custom fields.
That being said, I tried Divi once and quickly realized you can't achieve as much with an out-of-the-box drag-and-drop theme. However if you can't code your own custom theme, Semplice looks promising.
