I certainly don't think your opinions are invalid Bob. I also wish the SCP would bring up the choice when you touch the selection, I don't mind the linear selection instead of having a grid, though as huge as the ISO lists are getting, a grid might not be a terrible thing.
Bracketing not being able to be assignable to a button normally is a HUGE miss for me even though I don't do bracketing all that much.
I have used my neighbors GH2 pretty extensively and I'd say the DR advantage is closer to 1.5-2 stops. About half tom wo thirds in the shadows and around one to one and a half in the highlights. The shadow noise also has less chroma noise and is more luminance based (and less of it). I'd agree that high ISO noise is maybe only a single stop, but high ISO dynamic range is a lot more than a 2 stop advantage once you get up around ISO3200 or higher.
For IBIS, effectiveness is a wash really against OIS. If it matters to you of course with EVERYTHING is subjective and you mention you pretty much don't use any primes and/or rarely shoot slow shutter speeds wide angle, so IBIS likely dosnt matter for you. On the converse, for people like me who shoot almost only primes, IBIS is a massive, massive advantage as there are no OIS primes (so far and I suspect it is going to be a long time before we see any and might only be telephotos when we do see them).
Weather proofing is a lot better than the minimum rating you suggest, keep in mind, the IPX2 rating you mentoined is HIGH PRESSURE water from 15in. That is way beyond what you'd experience in even a torrential down pour. your pretty much have to blast it with high pressure nozzle on a garden hose to replicate. IPX1 will generally cover any kind of remotely normal rain for hours.
Otherwise on all the stuff that is truely subjective (IBIS, sensor quality and weather proofing are NOT subjective and the OM-d EM-5 is a lot better than the GH2 in those respects, oh and the EVF is a lot better too), that is of course what ever works for you, the EM-5 works for me in most everything else you mentioned and is better than the Gh2 for the reasons you mentioned the Gh2 is better than the EM-5 in all those subjective categories except the SCP sptouch selection and the bracketing. For the non-subjective stuff, the OM-D EM-5 is better except video...though if you need stabilized video it is better in that respect. Now if you don't need or want what the OM-D EM-5 has to offer over the Gh2 in those non-subjective areas, that of course changes how you perceive the camera and it seems to for you, which is truely fine and valid. I don't neednthensupperior video of the GH2, but the video image stabilization of the EM-5 is useful for me.
However, I will have to chime in and say the way you wrote most of your responses was more of a "I am going to be as dismissive of the camera as I possibly can be because I want my GH2 to be the better camera even if it isn't"
It might work for YOU better and for YOU it might be a better tool, but that doesn't necessarily actually make it better overall. I don't need a car that can go 0-60mph in 5s flat, but I can't deny that sports car is a lot faster than my 8s sedan...and hey I like the comfy seats in my 8s sedan more than the seats in the 5s sports car and the seats are a lot more important to me than being able to carve up the roads...however it sounds like through most of your review you talk about how the EM-5 is a 5s sports car, but "come on, 5s is really barely faster than my 8s sedan, so the sports car barely manages to eek out an advantage there".
