.com is the standard and is the "more professional" top level domain. anything other than a .com is inferior, and besides most people assume .com.
I prefer .com. The reason not because of the SEO (.com and .net doesnt affect SEO much), but the standard. People use to type .com and remember .com easily compare ot .net
there is a higher chance when someome hears about ur companys name they will try it as .com then .net if u know what i mean .com is the first thing peeople think of especially with a company.
