WPML and/or Polylang questions

Hello.
I am possibly about to make a multilingual WooCommerce site.

so the page already contains categories and products.

What i need, is to decide if i should use Polylang or WPML

so, i need it to:
– show the english product and page contents when there is no translation available for the target language
– if i change the price for one language, it would change the price for the other languages also (or an option to update it, [x] for example)
– An easy way to copy all the product details to the translated product while translating.
– If i post a link to the product online for example to social media, it should work right and show the correct language according to the users browser settings or pre-selected choise. (rather than having separate urls for different languages) if possible.

Whish one suits me better in this situation and are there any other cool things that are better with either one of them?
