Recommendation for fast WP plug-in for testimonials?

Hi GP Support. My small business site on Kinsta uses your premium plug-in. I also run Elementor Pro only for the testimonial slider plug-in. Nothing else. I can eliminate the plug-in if I go with static testimonials in the page copy.

I would rather use a testimonial slider. I also run WP-Rocket for performance and their blog post likes Nivo Slider and MetaSlider testimonial plug-ins for performance. I don't know how well they do with SEO. Lately Google has been finding my Elementor Pro testimonials on my site home page and using them in organic search results.

What do you think? Is the opportunity to get rid of Elementor Pro and achieve better mobile performance in Wordpress important? What do you think of the other two lightweight plug-ins as replacements?

I use your GeneratePress Pro and free Elementor on my site.

Many thanks in advance!
