Hi Vishal Goyal,
Regarding your questions:
1) Q: "Why this software over something like Total 3D Home Design?"
Answer: If you see 3D works elaborated with Total 3D Home (by Individual), you just need to compare them with the images of my Galleries
http://www.punchhelpers.com/galleries00.htmlTotal 3D Home (by Individual), doesn't export or import to CAD, first and necessary tool for a professional work. In addition, Punch has a framing editor, 3D workshop, Animator, etc
2) Q: "How are the images as compared to the competition? I am looking for very detailed graphics."
Answer: Again, check my Galleries
http://www.punchhelpers.com/galleries00.html3) Q: "Can you export the design and a "virtual tour" to a CD as an excutable?"
Answer: yes you can. Check my movie gallery

Answer: Do you mean the floorplans? In a addition of the BMP files, you can print to a PDF file or you can export to DXF /DWG (CAD files)
5) Q: "How long (approximately) does it take to create a custom design with landscaping? Let's say it is a 6000 Sq Ft home with 15 rooms and 3 levels. Landscaping would be for a 1.75 acre lot."
Answer: It depends. Who is going to design? Is the designer starting from scratch or is he/she importing a CAD plan? Is the designer a professional? Is the designer experienced with Punch? (as with any other sw, experience reduces the necessary time)
In addition, you must check the company support for your sw. IMO this is an additional great feature in Punch, as you can see in this Forum
