In power terms they are the same. The later, version 5, uses different heads and pistons to the Version 4 - but achieves the same result. In simple terms it is just an upgrade of the earler model.
A 5 will not go in place of a 4 easily and ditto vice versa. It can be done but what a load of hassle.
There are arguments that Vers 3/4 have better cams fitted than Vers 5/6. Again it is just a matter of upgrades and they achieve the same results in my opinion.
Pre September 98 cars need Vers 4 and post September 98 need Vers 5 That's the one fixed rule.
