What is the diffrence between EPS and PSD in making a mockup in: 1. Quality 2. Size in loading page 3. Easier to use 4. Similarity between both of them

The only annoying thing about FW for me is that the keyboard shortcuts are sometimes different from Photoshop.
It does not matter. Neither a .psd nor .eps are appropriate formats to just stick on the web.
Use whatever you are comfortable with in creation. Then you slice up your layout into pieces and build code (HTML/CSS) and use parts of your Photoshop or Illustrator document for any necessary supporting images.
In no case is a .psd or .eps file simply put on the web as a web page.
Update after question edit:
In terms of a mock-up, your question is far too broad.
For example, eps is a pretty dead format for most things, certainly for any web design mockup. You would use .ai or even .pdf before resorting to eps.
In terms of quality, there may be some slight differences. For example Photoshop will allow you to add dithering and noise to a gradient to soften banding. Illustrator can't do that. Or the fact that Illustrator can easily allow editing, and reediting, of rounded corners where Photoshop can't do that.
As for loading "size", that too makes no difference. Since you would be pulling individual elements and saving those, they file sizes of these elements can easily be made identical or nearly identical.
Easier to use... really depends upon your knowledge.
Similarity between AI and PS... check Adobe.com.
Of course, the mock-up is only part of the equation. Communicating what it should do in action is just as important, regardless of your art app. I gave a brief overview of my approach over on UX SE in this answer.
As a front end developer, I always side with photoshop on this one. Many designers forget to set their AI comp to snap to pixels. This leaves instances where boxes that are drawn with vectors hang in between pixel lines and output blurry lines instead of sharp ones. When you're designing a site that uses a column layout, these little bits will sometimes force a frontend admin in a dizzying fury as they'll have to go in and adjust things. This can add frustration between design and development teams and will ultimately impact deadlines if a frontend now has to jump into photoshop and correct things.
