Page builder help

Hi,

I’m putting together a WordPress store (using MarketPress) and I’m wanting to customize a theme including the backend. I’m looking at page builders – for visual creation using drag and drop. The 3 Page builders I have come across are Upfront, Visual Composer and SiteOrigin. I was hoping if anyone has any experience with these could you make any recommendations on which may be the best for the job? 2 of them are paid so I’d rather not buy them just to test out, so If anyone has already got them what are your experiences? Or is there anything else you know of which can do the same job?

Thanks

Aaron
