What do you like best?
For friends and clients I often have a need to produce simple (but good looking) websites. I've tried all of the big different drag & drop do it yourself website tools (Wordpress, SquareSpace, Wix). I've found Weebly to be the best compromise on ease of use and price.
I use Weebly when I need to get a website up and running very quickly, and don't want to spend a long time building a custom site. I can now get a basic website up for a project in a few hours. The main benefit is that the site will look good, modern, will automatically be responsive on mobile devices, and there is no hassle to maintain it.
Weebly is especially good when you are building a site and need to hand control over it to someone with minimal technical ability, as it's by the far the easiest for non tech-savvy people to edit. Anyone that can use Facebook has the technical ability to edit text and add photos.
A great feature of Weebly is that you can build out a site for free (on a .weebly.com subdomain) show it to all the interested parties and check everyone's happy before paying for a package to add it to a custom domain.
What do you dislike?
To be clear Weebly is not the most customisable option. Most of the time this is to it's credit - as there is far less to go wrong. But occasionally there are limitations that cause a hinderance to the basic usage of the platform - for example when you want to change a font and you are limited by what you can do within the template.
Whilst the pricing is very reasonable when you're using Weebly for business purposes, when you're using it for other projects (blogs, personal websites etc) it is a bit pricey. Especially, when additional (basic) functionality is chargeable on more expensive tiers.
It would be good if there were some more pricing plans for power users. Almost every month I have some charges for Weebly coming off my credit card (for one website or another), but with me having dozens of sites it would be nice to have a power user plan that charged me once for all my usage.
Recommendations to others considering the product
With all of these do-it-yourself website building platforms there are either free tiers or free trials. I suggest the first time you need to build a website that you sign up to all of them (SquareSpace, Weebly, Wix, Wordpress.com) on free trials and start to create the basics of your website. There's no need to build the whole thing, just choose a template and start customising it.
You'll soon see which ones you find easiest to use, and which ones will meet your needs. Then I would confirm the pricing you'll be paying on your favourites ones, and make a choice.

I needed to quickly spin up websites without the hassle of employing designers, developers and wasting time.
