5i25 is likely to be a direct pin-for-pin replacement. But then a pin-for-pin replacement doesn't buy you much advantage unless you are hitting a step-rate barrier.

So, the question back to you is what you want to get from the upgrade?

At the moment I am using three parports which provides enough IO pins .

Sounds like a 5i25/7i76 combination might suit you then.

Though the 7i43 hooked on to one of your existing parports probably shouldn't be overlooked.
