Hi William,
I like them all but, your last one would be my choice, also.
I don't know the reason but, the varnish coating on your first one is better than the rest, particularly on the top part, the last one you made, looks like you grabbed it before it was dry or it soaked a little more than the others.
I also don't know what type of finish you intended on them (natural wood look, a satin or a gloss finish) but, from the finish you use on your other pieces (I believe to be the same product), it may require another coat to cover some of those dull spots.
This is what I see, if I'm wrong because the pics are creating that effect, I apologise as I only intend to give you a true feedback of what I see, sorry...!
Cheers
George
