“My question is, does https take precedence over http when using google ? Should I change my websites to https as a matter of principle? ”
Googles search index algorithm is comprised of 200+ signals. HTTPS is just one of them. The amount of weight it carries varies depending who you talk to but only Google can tell you for sure.
What we do know is Google is focused on the web consumer experience and it has been very vocal about speed, security and relevant content relating to a users search query.
HTTPS addresses security so it's going to be an important signal. But page load times particularly for the mobile first world we are moving to are also very important.
Visit
Googles speed test page, compare your website and then your competition. Personally I would address these issues before moving to HTTPS.
Then look at the usual ranking factors, build some good quality links, active social media presence. I'd also question the need for multiple websites advertising the same service. If it was me, I'd consolidate and concentrate on promoting one site.
So to answer your question, don't change to HTTPS as a matter of principle, change to HTTPS as part of an ongoing an coordinated marketing plan. Your competition may look more amateur than your website in your eyes, but if it loads quicker, is more secure, and Google deems it to be returning relevant content for relevant search results, then that's why it will out rank you.
But never tinker, always sit down and plan any changes. Near the top of page 1 is infinitely better than the top of page 4
