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.
