It’s totally personal preference. Some people like Thrive, some Elementor, some Beaver Builder etc.. Personally I can’t wait until WordPress adds their own page builder.
It’s worth trying them all out and seeing which one works best for you – everyone will have different preferences depending on their work flow etc..
Miguel, I’ve paid for and used both. Thrive I used for over a year and really, really liked how comprehensive it is. It can do anything, really. Elementor I’ve fallen in love with simply because it’s so much faster to design exactly what you want, and the tight integration with GP is incredible.
