Need suggestions, which adobe program is better for website mock-up design. I am using Photoshop throughout of my career. But adobe community is talking about illustrator cc for website mock-up design.I just want to know your(web designers) preference.
First off, this question is asking a large group of individuals to provide a concrete answer on a topic that relies heavily on an individuals personal preference, application skill set and workflow efficiency. All of those factors can vary drastically from artist to artist.
In a nut shell Metis already answered your question, the same result can be achieved in either Photoshop or Illustrator. Realistically, it comes down to which program you are most comfortable and efficient with while simultaneously knowing and understanding the essential design requirements of the project.
Try Sketch (Bohemian Coding) it's the current top software for designing websites, apps and interfaces it is based on CSS and have many plugins available, some of them allowing for export to HTML.
However, Sketch is a Mac only product and they have stated that they have no intention of ever providing a Unix or Windows product.
If you want to create mockups with interaction you can also try Adobe Experience Design, it's a new tool for rapid prototyping:
Go from idea to prototype faster with Experience Design CC (Beta), the first all-in-one cross-platform tool for designing and prototyping websites and mobile apps.
It's still in Beta but pretty easy to work with.
