Not a standard e-shop. Drupal, Prestashop or Opencart?

Question

Drupal

Good afternoon,
The task is to implement a non-standard e-shop.
In addition to the usual list of products on the site, users will be able to add products themselves. Depending on the category, different product fields, etc. Leasing, various payments, deliveries, etc.
Also, not a small part is played by the convenience of using the system by managers.
We started doing it on Drupal 7 + commerce.
Difficulties arose immediately. You need to create a "display" and select products there. This is not very convenient for managers and there is a difficulty with "adding goods by users".
Roughly I described the project.
Need advice. Should I leave Drupal 7 + commerce for something else? If yes, then for what?
I think in the direction of Prestashop.
Thank you.

Answer 1

You need to write your plugin for Drupal (or other "store" CMS). Extending someone else's plugin is not a good idea. This will be quite labor intensive + you will need to periodically update your development as the plugin is updated by its developers.

Answer 2

I would love to write using the Yii Framework or Symfony2. But there is no time. Very limited in terms. Drupal refused. The choice fell on Prestashop.
Thanks for answers!
