Choosing upgrade way D7->D9

Greeting,

There is a site on Drupal7 + Ubercart3 + some custom common-purpose and ubercart-related modules.

I trying to choose a propey way to perform upgrade to Drupal9 + Commerce2 bundle:

1) Drupal7+Ubercart3 -> Drupal7+Commerce1 -> (optional) Drupal8+Commerce2 -> Drupal9+Commerce2

2) Drupal7+Ubercart3 -> Drupal9+Commerce2

(both ways with contrib and custom migration modules of course because migration of products/orders/clients is required)

Which way would be better?

Thanks in advance,

BR

I used composer to upgrade after disabling webform, since i don't use it anyway. After composer update ran successfully, drush status shows the following:
