My guess is you want to do the  {title} | {company name} format as I would suspect Google gives slightly more weight to the words at the beginning of the title?   (This is assuming your company name isn't a generic word or you are specifically trying to rank your home page for your company name when it isn't ranking well already) But what about cases where you have like 5 or 6 keywords that are really important and used in the title gives you like 50 characters and your company name pushed it up to like 65 increasing the chance Google will use some other source to list the name of your home page in the search results? Obviously one can experiment, but wondering what the general consensus is - long keyword title, or longer title with company name?  The company name can be included in the meta description and the domain name of the url displayed also gives the indication to the company.  But maybe the algo "respects" long itles that have company name more than ones without as then it looks more like a keyword stuffing title?  So many factors to consider.  Yes - on page SEO isn't just about the title, but for this thread I'm just talking home page title.
