Identifying Trustworthy Builders and Understanding Subsidies

Dear experts,
I am trying to understand how to find trustworthy builders in the Ethereum network. I came across a website (MEV-Boost Builder Profitability | that shows the top builders and I am wondering if it would be a good approach to send transactions to the top 10 builders listed on the website. I am also concerned about the potential danger of miner extractable value (MEV) and how it could be used against searchers.

Additionally, I am curious about the economic reasoning behind builders using subsidies and would like to know if there are any red flags to look out for in this regard.

I would greatly appreciate any guidance and information you could provide on these topics.
Thank you for your time and assistance.
Best regards.
