I found your blog post from last year https://premium.wpmudev.org/blog/most-popular-free-wordpress-slider-plugins/ with a wide selection but I have used layer sldier and revolution slider for a client (they came bundled with his theme) and have seen a lot of nice features like layers adn the ability to customize every tiny setting.
I'm looking for a slider that has it all: HTMl in sliders, layers, the option of showing recent posts inside a slider, the option to make each slider responsive or not, full-size, etc.
I don't mind paying, just need to be pointed the right way as I'd hate to try a free one then rebuild all my slides for another slider if I decide later on to buy another one.
Any hints/pointers? Maybe recommend 1-2 you'Re using and I'll check them out.
