Should I stick with my current email settings?

[Octavio]

I have many email accounts, yahoo,AOL,Hotmail,Google, etc. I also have certain accounts associated with them, like this site, Facebook, twitter, and others. When I created my YouTube account I needed a Google account to use it as it was bought by Google. Now since my current phone uses many stuff associated with Google, my Google account is my most used. Based on that, Should I keep the current settings or switch to more often used emails like Google?
For example, if I had Facebook and twitter using my yahoo email, should I switch it to Google?
