I like statues better for a few reasons.
1) 1/4 size. No matter how good something is, the 1/6 scale still looks like a child's toy to me....which is appropriate I guess since that's where that scale originally comes from. (not saying HT's are now)
The 1/4 scale is so much more significant as a show piece and fits in to rooms like other display pieces (vases, paintings, etc)
2) I don't have the need to repose constantly. Honestly, I don't know how many people do really. Sure its nice when you first get a 1/6 figure and you might do a few poses in the first week ....how many times after the first month? The second? For most its close to zero.
One of the more bizarre things I see here is people that like the articulation but would never pose anything (or even take it out of the box) due to fear of deteriorating.
3) The sculpting of the human body is important to me.
I'm a long time martial artist and was a personal trainer for a while as well.
Joints ruin collectibles for me. I want the body to look natural.
Fully clothed its not so bad, but even so the body underneath the clothes is set facing forward and so never looks quite right posed any other way.
The new Terminator statue is a good example of a clothed statue. You can see the lat flare holding the arm up and the neck muscles contract as he turns his head.
And when it comes to shirtless, well there is no comparison. My 2 Bruce Lee's, Indiana Jones and the Temple of Doom and Conan would just look like toys with big ugly joints every few inches.
4) Also polystone looks so much nicer than the 1/6 plastic generally used ....though saying that the 2 HD 1/4 Enterbay Lee statues I have look very nice in whatever they are made of.
And this could change because its more tradition than anything, but I love the giant detailed bases that Sideshow PF's generally come with. Its not really part of Hot Toys 1/6 offerings for some reason.
5) This one is only coming about recently but the 1/4 statues are looking better and better in terms of value for money as 1/6 figures continue to skyrocket while SS PF's stay relatively the same.
And somehow Enterbay lead the way here!?! Expensive 1/6 figures ....but their HD Bruce Lee statues in 1/4 scale are under $200.
I'm hoping this isn't going to change with the introduction of their HD T-800 which is articulated. Although that is great looking, I hope EB continue to release their HD statues as well.
