What to choose for a back-end medical portal?

Question

PHP

The guys have a medical portal, with a complete database of diseases, a database of drugs and pharmacies.
So we decided to rewrite from scratch, but we can’t figure out which platform to write on.
Functionality is lists of diseases and drugs for treatment. Drug analogues. List of pharmacies and medical institutions.
Loading huge prices in the database.
I understand that the question can lead to holly war, so I will highlight the key points.
Necessary:

• Sustainability
  
• Code readability
  
• Execution speed
  

Answer 1

Sustainability - any mainstream language
Readability of the code - it has nothing to do with the language or platform, you can do bad things anytime and anywhere.
Execution speed - again, you can take java and kill all performance with locks, thoughtless work with threads, stupid algorithms, etc. It is also possible to write different parts of the system in different languages, depending on the requirements.
In a word ... that's what the developer knows, then you should take it. Or, again, at the discretion of the developer.

Answer 2

Of course, I will answer you what you do not want to hear and I will not receive a green tick on the answer, but there is no difference.
That is absolutely.
What kind of (good, of course) programmer is at hand, what technology does he know / prefer - and write on that.
The quality of the final product does not depend on the programming language , but depends on who will implement it, on his qualifications.
If you are a customer, then do not deal with issues that are not characteristic of you , let the contractor decide.
If you are a performer, then you need to write on what you know best.
