I put barbs on as I feel it makes it eaiser to work with. It look better to, not so hacked, if you know what I mean.
As long as it doesn't leak you are fine.

Well it doesn't make a difference, it still get jamed down to the smallest fitting.
Only as strong as the weakest link. I know you have heard that one before. Same rule apply here.

So why add more links? 
I'm not a fan of putting barbs on the heatercore as long as it's reasonable to stretch your tubing over it. You get less flow restriction, it's less work, and it doesn't look bad at all.

i used larger tubing myself
i change to 5/8 id for the heater core then reduce to 1/2 tubing
slides on easier

Thats the thing you don't get less flow restriction. You still have 1/2" barbs other places in the system, thats where it get backed up. Just becuase 2 of the fittings are larger does not mean that it is still not limited by the other 1/2" fittings.

yup
it is only as fast as the smallest barb(or tube)
or
flow is no faster than the smallest restriction
but i used two size tubes because it was an easier fit and i am lazy

ease of use
they want the tubes to go on easy or they like the looks
mine look great at the pipes coming out(5/8 id tubing is huge)
but i have a reducer inline from both sides
from 5/8 " to 1/2 "
that looks kind funny but it cool

Very true. 10 half inch barbs will have 10 times the resistance of a single half inch barb.
Restriction is also a function of the length of the restriction. A half inch hose barb is relatively no big whoop.

Thanks uberblue. Stretching the tubing over the heatercore barbs will still cause less restriction - maybe not much, but every little bit counts.
