Do Woocommerce and Shopyfy offer the option to integrate unlimited products and wholesaler plugins and csv support, and which system is better?

Hello

I'm thinking about becoming self-employed again with a web shop.

I used to use Gambio and JTL Wawi.

I would now like to use JTL Wawi again if necessary, but not Gambio or JTL as a shop system (unless you specifically advise me to do so), but rather Woocommerce or Shopyfy, as many wholesalers with whom I would like to work in the future offer a plugin for these two shops.

But now I have the following questions

1. Can both shops hold an infinite number of items or which of the two shops can hold the most products?
2. As far as these wholesale plugins are concerned, these shops can accept an infinite number of plugins so that you can integrate multiple wholesalers. Would duplicate order numbers then simply change or would the entire article not be read in? Or is it only possible to integrate one wholesaler?
3. Can Shopyfi or Woocommerce automatically read CSV files and does it also have other reading interfaces such as API,…?
4. Can all payment providers and shipping companies be set up or connected?
5. Can all price comparison portals be connected, such as Kaufland, guenstiger.de, etc.?
6. Do both have a JTL Wawi interface?
7. Can different shipping countries and their shipping prices be stored?
8. What are the advantages and disadvantages of the two in comparison and which of the two would you recommend and why do you recommend one and not the other?

I look forward to your answers and thank you

Kind regards
