That's too vague to be of any use. What tooling? What benchmarks?

The fact that you like SSMS doesn't really say anything about tooling for PostgreSQL. I find the quality of PostgreSQL tooling great.
There is certainly plenty of reason to believe PostgreSQL is superior to MS SQL [1]. I don't agree with everything in the referenced article, but your claim of MS SQL being far superior is, so far, completely unsubstantiated.
As I’m sure you’re aware, publishing benchmarks of commercial RDBMSs is usually prohibited - I’m just passing on what I’ve heard from an expert about query optimizers.
Interpreting the questioning of your grand claims as combative should tell you something about your own attitude.

I only know that MS and Oracle prohibit publishing such benchmarks - and that's yet another reason not to use them.
Tooling and speed. I can vouch for the quality of SQL Server's tooling – SSMS is very nicely integrated with SQL Server.
If you watch the CMU DB Group's lectures on YouTube, they mention that the commercial RDBMSs have put a lot more time+research into query optimization than the open source ones (and apparently SQL Server has the best optimizer).
