I have used the push type on lighting circuits here - since the load is not that high, and the convenience counts for a lot when working through small holes in ceilings while up ladders etc.
I was also wondering how much the enclosure counts for keeping the joint corrosion free - the push fit terminal housing is a far more protected environment than that provided by a bit of chock block.
On a lighting circuit you can stick 2x 1.5 and 3x 1.0 mm T&E into each end of a blue crimp IME.
