Which web design software is best on SEO point of view?

Hi guys I hear that our site's SERPs also depend on the coding of our website. It is because search engines view our site's coding when they crawl it. They are said to give importance to the sites which are coded well. I hear the design from sitebuildit is the best at the moment as far as the SERP's from the coding of site is concerned. But they are kind of expensive. Do you know any website design software which is good on this point of view? Like Dreamweaver, xsitepro, webpagemaker etc. Please let me know what you think of these softwares. Thank you.

web sites are crawled better if they have meta tags with them.sSo it is not based on which software you have used but amount of meta tags used.But still,dreamweaver should be opted on the safer side
