Translation:There is one big difference.
'Big' is fine. One difference or a difference? A big difference reads better to me.
we can use huge also but system does not allow it!
It does in 2018
yes .... huge is much better english
or a "great difference"
Great difference was not accepted 2014-04-19

"There's a great difference" is accepted.

There is no possibility in the pre-chosen words to mark - a- !
No - but there is to say ONE big difference. Took me a minute too!
