I don't know if you've ever worked with MS SQL Server in production but for us it's been the most amazing piece of technology in our stack for the past 15 years.

SQL Server is in the top 3 best things to be published by Microsoft ever. (The other 2 are probably Excel and Flight Simulator)

and SQL Server BI stack, is very solid and cost effective SSRS is really good SSIS is very acceptable (I mainly use to call SQL Tasks) and SSAS is really second to none

SSRS still doesn't have support for msbuild, SSDT is a goddamned dumpster fire, and SSIS jobs have that hilariously over designed graphical programming language and are do frustratingly brittle that they are functionally single-use. And SSMS has the worst use of tabbed files I've ever seen.

There's a link to like about mssql, but a lot to hate too.

What's so amazing about it, when compared to the other SQL DBMS's? (e.g. postgresql, oracle, sybase, db2, etc)

Especially as it's just a re-badged Sybase...

You still think of MSSQL as 're-badged Sybase'?

You know that was literally DECADES ago right?
