Difference between buying aged USA account and creating one yourself?

I am looking into USA TikTok and X/Twitter.

There are a lot of sites that sell aged USA accounts for a cheap price, but looking here I also found out that a lot of people go through the hassle of buying a USA sim, a new phone, setting up VPN and proxies just to create a USA account (all these, when added up are a magnitud more expensive then than aged USA acc).

Can someone with expertise elaborate what are the advantages of one approach or the other?

Buying aged accounts can be risky but old accounts tend to be trusted more by social media platforms compared to new accounts that had just been created.
