Maya was not really and still isn't targeted at the Arch-Viz industry and never will be, it's animation/game/film/motion gfx orientated and always will be. But having said that, there's no one out there saying you can't use it in the Arch-Viz industry because you can and undertneath it all, it's still just a 3D package but it has shortcomings that Arch-Viz projects can require. Off the top of my head compared to Max:
Max has better modelling tools, no doubt about this. Maya is one the worst modellers in 3D at the moment with only minor additions over the last couple of years, the loft tools haven't been updated since the 90's, creating roads on terrain is nearly impossible if not for manually intersecting roads (no drape mesh like in Max), the booleans don't work on anything but watertight, clean meshes, the extrude along path tool breaks on hard edges unless you have an insane amount of polygons, the linear workflow is half implemented in most renderers, the scattering tools that have been on with Max are now just available this year, there are no native 3D arch-viz libraries that exist for Maya, no instant roof plugins, no instant floorboard generators, no random color generators, no IES prieviews in the viewport, It was only a few years ago that V-Ray for Maya did not exist and users had to put up with mental ray for Maya (which if you have used, you will understand), etc.. etc...just off the top of my head.
That being said, I make a living out of Maya for Arch Viz and it is easy once you write your own tools and get an effecient pipeline going! I try and model most stuff in SketchUp as it wipes the floor with Maya when it comes to modelling, Maya, however, is much better than SketchUp at texturing, adding details and handling huge amounts of data. I only chose Maya due to learning it.
On the other hand I I think it would be annoying to use Max and rely heavily so much on plugins, upgrading them all every year must be a pain. One plus is that with Maya, it's easy enough to write Tools, library managers, importers whatever you want. A bit more work, but it's nice conforming it to how you work.
PS I was about to post saying no way AD bought Maya in 2005, but there you go! Seems like it was much more recent than that!
