It's the D|S users that you can accuse of fanboyism, not the Poser users, because they are the ones who try to rationalize a crippled and incomplete program as being an actual "option" comparable to Poser.

I couldn't care less about EF or SM or whoever currently owns Poser.
If someone brings out a program tomorrow that could do everything Poser can but a lot better, I would switch in a heartbeat.
But I'm only willing to switch if the new program would give me more options, not less.
And create more realistic looking characters, not "Aiko realistic" wannabees.

The beauty of Poser is that YOU DON'T NEED TO BE A PROGRAMMER to open and hack a cr2 file. All you need to do is know how to read.

And yes, Poser uses python to execute scripts. Have you checked lately how many FREE python scripts for Poser are out there ?

So that DAZ gives away the D|S SDK for free while you have to pay for Poser's is completely irrelevant, because "normal people", i.e those without a programming background wouldn't know what to do with it anyway.
BTW, ".obz, .pzz, .crz, etc" are just zipped obj, pz2 and cr2 files. Just disable file compression and they're gone.

And comparing the P7 Morphbrush with D|S "D-Formers" ?
Well, I guess then you better DO stick with D|S if you can't recognize the difference and what breakthrough the morphbrush is for Poser users who want more realism.

Yes, maybe one day D|S will be able to read morphs BEFORE it reads joint parameters so they can provide the same functionality as the morphbrush, but then they'll still be stuck with magnet infested V4.1 and their derivates.

Speaking of V4.1, I could give you dozends of examples where she is inferior over V3, but here are two very obvious ones:
There were a lot of V3 hybrids out there: V3's head on Posette's body, V3's head on V2's body, V3's head on Judy's body.
Why ? Because all those figure's heads, mouths and tounges were a single part so that they are easy to swap among them.
No extra rigging or complicated cr2 editing involved.

Now with V4.1, you get a head, upper teeth, lower teeth, and SEVEN tounge parts, all individually rigged.
Try to put V4.1s head on another body and you suddenly find yourself confronted with a a lot of extra rigging and cr2 editing necessary without any measurable benefit over more "simple" figures like V3.

Another example:
A lot of people made free textures for V3. A V3 texture is fairly easy to make in Photoshop because all major body parts are scaled similar so it's easy to paint over seams.
Now with V4.1 the bodyparts are scaled all over the place. Result: Without buying a full fledged 3d painting program it is impossible to create a proper V4.1 texture without noticeable seams.

I predict there will be A LOT less (If any) V4.1 hybrids out there, and a lot less free V4.1 textures.

And the ironic thing is that neither "modern" D|S nor "modern" V4.1 can deliver one iota more realism over "ancient" Poser and V3.

Nope, DAZ started a race for the bottom line, because that's where they think the money is.

The Poserverse is so big not because of DAZ or Renderosity or any other marketplace.
It's big because Poser made it possible for each and everyone to participate because it gives you all tools necessary to truly CREATE.

And only a program that gives you all options and doesn't lock the "non-professionals" out will keep it that way.
