Please can some seo expert finally answers this: Does "Google crawling machine" prefers .com domains over other TLD domains (.net, .org...).? Most people say: 1st choise is .com. But what Google "says"? If I type "health" in Google, then within first 10 results are: 5x .com, 2 x .co.uk, 1x .int, 1x .org. and 1x .gov. From this I believe that other domains are "respected" pretty as much as .com.
I'm no expert but .... I don't think com TLD gets any preferential treatment; other factors dictate the "likeability" for the bot and algos. i.e. A Google search for "Webmaster info" = top ten results are mostly Google, but there are three .info site references too.
