Shopware vs. Shopify

I would like to create a shop with around 1000 products, most of which have several variants (shape, color). Almost all providers want to work with Shopware 6. One provider said the system was still too buggy and that he would use Shopware as a basis, but implement the shop using Shopify. Does it make sense? Is Shopware 6 really too immature to build a shop on? Said provider is an acquaintance who said, according to his principle, there are no weak points (unlike with a pure Shopware system) As I have understood, you can design Shopware more according to your ideas using codes and Shopify has a simple modular system, but also requires 2% commission from sales. Maybe someone here can refer me to an alternative source of information or another subreddit. Thanks in advance
