P30 or Mate 20 Pro?

I currently own a Huawei P9 and consider buying a new phone. Since I'm very happy with Huawei I think of a P30 or Mate 20. Now my questions:

Is an advance on the mentioned phones visible in comparison to the P9, so that a purchase would be worthwhile (especially the photo / video quality with front and main camera, battery life, charging time), not only from the values, but also in practice?
Are there any other reasons for (k) a purchase?
Is it worth a Mate 20 Pro or P30 Pro or rather the "normal" version?
Should you currently buy a new Huawei (US trade dispute) or should you wait and see?

I look forward to your reviews & comments and thanks in advance for your answers.

I would let go because Google and Hauwei are currently not working well together which means hauwei is not getting any more important updates

Personally, I would not mind Huawei's more hollow mine constantly erasing all data from my sd card, etc (p10 lite)

Find the New range of Samsung real class A40,50,70

Look at it vlt time are price not synonymous so expensive and the camera has a mega resolution werd me too soon so one hollow.

Huawei p30 is really a very good device. The trade dispute is over if you did not hear it. Trump had a settlement with Huawei and thus Huawei may continue to use everything normally.

Thank you.

Is the P30 Pro worth the price-performance ratio or rather the P30?

At Samsung I was with my former S3 Mini not very happy with the battery life. Even with the Samsung S6 Edge, the battery was unusable relatively quickly. Is that better with the models?

I do not even look at a comparison on google and look there since iat the battery life and performance all stated.

I would tend to the p 30 pro.

What complete nonsense is, I think there you should again research.
