I'd have to see my favorite part about SSRS is the "clean" export to Excel.
I worked with Crystal Reports, version 5, in 1996. Let me tell you, the export to Excel was anything except clean.
And when you called for tech support, they always promised the next release would fix the problem.
Well, SSRS got it right from the beginning.
Possibly because they own the product.
And the operation system
And Internet Explorer too.
I'm not saying they are a monopoly, I'm just saying that the export to Excel is to my liking
And my customer's too.
That is all!
