What is the best website builder?

To understand your need well, let's rephrase. You need to build a website where you'd want to market customized snow globes (or other product). The end goal is also to sell.
What you'll need is to build a workflow for each of the product you wish to market which includes the base product, and then one or more customizations. Also I believe your products and customizations will change over time and you'd want a way to make those changes yourself.

If yes, please explore Woocommerce for wordpress. It's a plugin for wordpress that'll allow you to build end to end ecommerce site. https://woocommerce.com/

You do not need a website builder. You need an e-commerce platform, since your end goal is to sell online. Therefore beyond the visual storefront online and the customization you want, you need a backend:
1.) connecting to payment provider
2.) process orders
3.) sends invoices
4.) keeps track of your inventory
and more

Although WooCommerce has proven quite useful in the past and still today many shop owner use it, I would definitely recommend Shopify (shopify.com)

The reason is Shopify is an all-in-one service provider when it comes to e-commerce solutions. It is the Swiss Army knife of e-commerce shops so to say.

You not only get beautiful templates out of the box that you can easily edit with a drag and drop editor. Even more important sometimes, you get a premium server infrastructure with a team taking care of any necessary updates and technical issues, defending the servers against cyber attacks and making sure that every shop can scale from 1 user to 1 million users.

When people choose Wordpress + WooCommerce they focus on the free aspect and forget they need hosting and have to figure it out themselves. Also since Wordpress is completely open source it is more vulnerable to hacking, since hackers can study the whole code. Since Shopify is a business it also keeps its core code to itself and while advanced users can modify almost everything with code it does not allow users to modify certain vulnerable areas for this very specific reason.

If you want to build your online shop fast and focus on your business and less on the technical side I would strongly recommend to choose Shopify. They have a 14 day trial (no credit card required). The options might look a bit overwhelming at first but they even have a wizard to guide you through the process and a free online academy:

I maintain three businesses and I use wix.com for each one. With Wix I am able to choose from a plethora of templates (tailored to suit the category my business falls in) and from that template I can easily manipulate the website via Wix Editor. It is very user friendly and has a very extensive help center for every function on the website.

I like Wix because when my customers place orders, Wix automatically sends a thank you email, I can easily send out tracking numbers and if for any reason (God forbid) I'd need to give a customer a refund there's a button literally that says "Refund." Wix is as simple as it gets and your websites can still look professional and get everything you need done from displaying your products, to highlighting your services, to setting up booking for clients. It's that simple.

There are so many website builders available online. This builder can grow your business from zero to a hundred.
Wix is the clear front-runner in the race for website builder dominance. It's the biggest player with over 110 million websites built and boasts the greatest quantity of tools, capabilities, and freedom. Wix covers the full ease-of-use spectrum by offering an AI-fueled automatic website creator on one end ("Wix ADI") that requires minimal effort from the user, all the way to Wix Corvid, an open development platform for advanced applications like Javascript, databases, and data-driven dynamic pages.
Squarespace strikes us with one of the best UX and UI design. When you compare between Wix and Weebly in terms of ease of use, though it did get consistently positive marks from reviewers for the quality of design. Where I really think it really might shine is for small- to medium-size businesses who want a nicely designed page and room for e-commerce growth with lower transaction fees. When most people talk about WordPress, they're usually referring to the free open-source software available through WordPress.org. That's very powerful, but it takes some time to learn and still requires that you find a website host and domain name. If you're not interested in going the advanced route of WordPress.org, I feel hiring an experienced WordPress developer is the best solution for that.
