Now with my 406 should i just stay with the breakaway torque converter or
step up to the streetfighter?
which would you chose and why?

Of the two I would choose the 3000 stall converter. To explain why I'll use
the graft below. The combination is not an exact match to yours but the point
can be made regardless.
In the graft look at the dead area between 3750 and 4250 RPM. For best
acceleration for straight line performance, I always choose a converter
above this dead area, for the example below I would choose no less than
4500 stall.
Your power band will be lower with ~10 degrees less camshaft duration. My
choice would be 3500 stall minimum assuming maximum acceleration is the
goal. This is base on zero wheel spin.
