Answer 2

I think the first form sounds better than second. Even though we use both forms in Spain... For me the correct way to say this is: estoy seguro de que...

corrected 'even though' - billygoat, Jul 21, 2011

"I think the first form sounds better than **the** second" - billygoat, Jul 21, 2011

Answer 3

I've always heard both and taken it to be quite literal

estoy seguro que viene mi hermano (a possibility that you are confident about)

I am sure that my brother is coming

or

estoy seguro de que 2 por 2 es 4

I am sure about 2x2 being 4 (a fact)
