Not to mention that apparently if you turn off route-caching completely,
you will make a router out of any "l3 switch" (since all packet forwarding
will equally slow)

I don't understand how you can differentiate between a router and an L3
switch. In my view "L3 switch" is a marketing term. All high end boxes
do hardware based IP forwarding, whether their ancestry is from the L2
or the L3 side.
   


To me something that uses hardware assist, setup by the cpu per 
destination, is an L3 Switch. Something that does equal route lookups per 
packet all the time is a router.
