Performance is not the first rule on programming.
The first is: minimize design errors, programming errors and bugs

I use @table variables rarely.

But it can to be usefull to implement a good programming model.
If you call a black box sp out of your control and you wish a local stack table,
a @table variable it is the only choice.

For the MSSQL's parallelism, to be honest until now I have seen more problems than benefits
