When I'm driving in a Fiat Uno next to a Ferrari on the highway and we're both going 60mph, I could say; "Look, there's no difference between both!"
In some respects and functions, there is no difference. In others there are big differences. More useful is, they are different tools used for different tasks.
If I had both, I would drive the Fiat (actually wouldn't, but for the sake of this post) sell the Ferrari and buy a few good lenses.
