Hello,
Systems like Stripe or Braintree require to create the plans (duration + prices) directly in their system ; Maybe we will see if we can find a good solution to integrate with that kind of structure but I admit that it complicates a lot of things because HikaShop+HikaSubscription can be a lot more flexible.
So, in a first time, we prefer to see integration with system which can store the "card token" and process extra payments.
In such kind of integration, the customer will give its consent and new transaction will be made on the recurring day thanks to a cron task.
Now if you do have some payment platforms in mind, which support recurring ; we will be happy to take a look and see if an integration can be made.
With HikaSubscription 2.2.0 you have settings for the "optional recurring".

Thanks to optional recurring, you can have recurring and non recurring payment methods in the same time. If the plugin handle recurring, it will indicate it to the customer (and perform recurring payments) and otherwise, the customer would have to renew manually its subscriptions.
Please note that Paypal recurring perform the recurring only on the prices for the recurring products ; your order can contains classical products, they won't be include in the recurring (and that's a point which is difficult to handle with other systems).
Regards,
