elementor

Hi there! I want to establish a macro blog. I will use elementor for this purpose. But I got stuck in the choice of theme. I'm looking for a theme that is compatible with elementor and is light weight. Would love to hear suggestions.

I am using premium Flatsome theme from Themeforest but I heard that there are themes using UX or Elementor Pro is better or has better advantages. is that true? What is the best page builder for Wordpress?
