When deciding between a high aged domain with zero backlinks or a recently expired domain with a high number of backlinks and low spam score, there are a few factors to consider.
First, it's important to understand that the number of backlinks a domain has is just one factor in its overall value. A domain with many backlinks but poor content or a bad reputation may not be as valuable as a domain with fewer backlinks but high-quality content and a good reputation.
That being said, in general, a domain with a high number of backlinks and a low spam score is likely to be more valuable than a domain with zero backlinks, even if it's a high-aged domain. Backlinks are a major factor in search engine rankings, so having a strong backlink profile can help a website rank higher in search results and drive more organic traffic.
However, it's important to carefully evaluate any expired domain before buying it. Make sure to check the domain's history to ensure it wasn't used for spammy or unethical purposes in the past, as this could negatively impact your website's reputation. Additionally, be sure to thoroughly analyze the backlinks to ensure they are high-quality and relevant to your website's niche.
