So what's the question, exactly?
I don't know File Buddy, but EasyFind is good for deep searches, but takes an age to complete.
Spotlight and Finder work on indexes, and for that reason are very fast.
Try using the Finder filter bar for searches on file types. You need to hit the '+' button (it's shown as '-' button in this screenshot, but it's in the same location), clear the search field, then explore the options from the dropdown menu. "Other" has a lot of powerful search filters.
