I'll bite. I don't have any of the iem's you have listed except the GR07 (I have the MKI original ones). I have however had the HF3 (HF5 w/mic & controls) and it's easy to tell you to stop the debate and get the GR07. You will not regret it. I also have s4i's, RE-272, etc. Just as reference.
I say the GR07 because it's really an audiophile staple. It is unique and SO much better than it's price point. Just my .02 but I just cant see someone not liking them and they don't require you to have anything better than a Zune, Clip, or 5th gen iPod or similar to still sound really, really good and certainly leaps and bounds better than consumer grade. All while having room for MUCH better sources and amping wil only improve th quality. They have bass, but not just that. It's tight, clean, extends well with excellent attack and decay. Pointed treble with a touch of sibilance (MKI at least, never heard the MKII) but clear, un-muddied, well positioned and defined sound. Wonderful with guitars, pianos, bass drums, violins and lots more. Examples of greatness, Flobots, Hoobastank, Daft Punk, 8 Bit Operators, Paolo Nutini, James Morrison, Adele, Nirvana, The Roots, etc. They are really well balanced.
Compared to the ETY's they wont be cold, clinical and they are not analytical but thats not in anyway saying they are soft. I actually went to them right after my HF3's, they were the 4th IEM I bought in 5 months and then..... I didn't buy anything else for a year (you see where this is going).
Best of luck (that got long quick). Hope it helped.
