As it was explained to me, the main difference is that you can have $lots of prefixes in IS-IS without it falling over, whereas Dijkstra is far more resource-intensive and as such OSPF doesn't get too happy after $a_lot_less prefixes. Those numbers can be debated as you like, but I think if you were to redist bgp ospf on a lab machine you'd get the point.
Both OSPF and IS-IS use Dijkstra. IS-IS isn't as widely used because of the ISO addressing. Atleast thats my take on it..
RIPv2 is great for simple route injection. I'm talking really simple, just to avoid statics.
And there, my friend, is the crux of the matter. There's almost no place imagineable where injecting routes from RIPv2 is superior to statics. Owen
