The problem with the argument that you are making, that with more models Apple would outsell Samsung, is what others have said, there is no way to legitimately prove it. And providing another example is difficult because there isn't really one that is applicable enough to prove the point.
There are too many factors that are can't line up to other products,
IOS vs Android, which one someone chooses before they invests $$ into apps and docks and things has a huge factor on the decision to upgrade to a new phone, if someone invested in IOS wanted to go to Android, they would have to buy everything new again, thus costing more, and vice versa, the only comparable example would be computers or video game systems. Computers don't work because there are more Windows laptops than Mac laptops and the Windows ones outsell Mac ones. Video game systems, could work in this example but then the argument is there are 3 companies to compete with and which would be Apple in this case.
Form Factor, Android has many different form factors and sizes to choose from, anything from 3.2" screens to 4.65" screens to slide out keyboards to dual screens to blackberry style form factors, and Samsung makes one of each, except the dual screen, Apple has 1 form factor. If Apple decided to make an iPhone with a slide out keyboard, I imagine it would initially gain some sales from people who would buy the Samsungs with a keyboard, but its impossible to tell how many, and again there isn't really an applicable example to show this happening. Computers don't work, Video Games don't work, cars wouldn't apply, theres no example that would apply to the argument being made.
So in conclusion, if Apple produced as many models as Samsung, it is impossible to prove that they would outsell Samsung, and it is equally impossible to say that they would continue to not outsell Samsung. But to say that because they sell more per of each model than Samsung so therefore are doing better, doesn't really work, because they are still selling less product overall, and in reality, the more product you have in the hands of consumers the better your doing.
srry if this is a bit incoherent its 2am and I'm half a sleep
