Thanks again to everyone.
Results so far :
Set 1
-------
#1 - 4 counts
#2 - 2 counts
Either - 2 counts
Set 2
-------
#3 - 2 counts
#4 - 1 counts
Either - 0 counts
For Set2, I think its the bit longer FL of the lens for #4 that makes the lone leaf only partly in focus compared to the sample #3.
Interesting to me then that shallower DOF does not always mean better shot if the DOF is not enough to envelope the subject. (almost a religion here in a FF argument)
I do like the shallower DOF and rendering of #4 though.
Too bad I did not step back when shooting #4 to get back the same DOF. (something to note)
For me, same as Set1, I like a bit of both, 50/50 in fact.
(just can't make up my mind, which is a reason why I posted this blind test too)
