I want to rank all of product pages in Google with the same content

Hello Folks, I am working on a site (not e-commerce), which has detailed information about various products. For every product, there is 3-4 other alternative product available in the market. So for pages of alternative products, there will be exact same content. ABC, PAQ, and XYZ are three product names which are also the primary SEO keywords and will have the exact same content with just change in product_name. I want to rank all of these product pages in Google with the same content. All the product pages have the same importance and have different ranking keywords (with product name). So my question is, do I continue using the same content for different product pages or have to do something else to not hurt my SEO. I have already made experiments by using the same content on 2 different products pages and both are ranking in Google search result when I am searching with their product name. I don`t find canonical tag helpful here, because there is no root or one primary page. I want to rank all product pages on their respective search term. My competitors are also using the exact same content for different product pages. So what should I do? Please guide me
