Since I can only go on what I seen in person or own...
1. T-850 Terminator (Arnold Schwartzenegger) T2 Judgement Day Cinemaquette - This piece is truely amazing. Cinemaquettes are the only mixed media pieces that go above and beyond that of Sideshow's version, their 1/4 Premium Format line. As one should suspect from a MRSP of $1,199 USD!!! From the sheer heft (50-plus lbs) to the uncanny realism (actual real rooted hair (correct me if I am wrong)), to every spec of detail in his tailored outfit, there isn't anything I think comes close to besting this beautiful piece.
2. Gruson's 1/4 mixed media (Christopher Reeves) Superman statue - Uncanny likeness of Mr. Reeves from his face to his physique. Even his costume screams the 1970's, which has been fully capitalized by the fact the very first Richard Donner Superman movie was done in the late 70's. 1978? I don't know how old this piece is so please be easy on me.
3. 1/4 Premium Format Doom w/Chalice - This was probably more-so from 2005. Again, I am sorry if I am a noobie at this. After all, I just started collecting Sideshow statues months ago. I didn't even know of these forums until about this past month. Anyway I am putting him in my list because I need to let others know, what we all know already. He's probably the PREMIUM Premium Format. Everything about this piece screams gorgeous. From the detail, to the actual size, to the insane amount of love and attention applied to Doom's throne, to the character itself.
4. 1/4 Premium Format exclusive edition of Punisher - Love the abundance amount of accessories he comes with. Infact as 1/4s go, he's up there with the best of them. I love how the finest little details were applied to all of his weapons. So accurate to the real mccoys. Whoever sculpted this statue knew a little something of human anatomy. The way everything is proportioned correctly, to the muscle seperation in his arms. As a competitive body builder I have a great eye for muscle definition and his arms in certain photographs look so real, if you weren't looking at his face or anything else you swear they were (real). And now I am a proud owner of him!
5. Darkness Bust - The thing is huge and looks like it could be the centerpiece to any collector's collection. While I may not be into 1:1 scale busts, I must say he looks outstanding. I've only seen pictures, but when your eyes are always drawn to it over other pieces that are very exceptional, you know you have an instant winner. This despite the fact I am neither a fan of 1:1 busts or the character.
Next year in 2007 it looks like these bad boys could end up earning 2007 Statue of the Year honours...
