Like hammers and guitars, they're just tools. And, whatever tools you get used to using sways the user's opinion of other tools. If I am used to a lighter shorter hammer, a longer hammer will be awkward to the hand, even if the longer hammer is more expensive. And, guitar players will have their own idea of "quality" pending the playing style that they developed with earlier guitars. I personally like wider necks on my guitars, whereas the more expencive guitars will have more narrow necks, so I am not as fond of most of the more expencive one's (thank goodness).
There's no one magic formula for what makes a pipe better. It really is just up to how your smoking style developed with earlier pipes. This is why when one person says that they have a gurgly, crappy smoking pipe, someone else can step up and smoke it like a Stradivarius.
That said, just as a hammer can have a loose head or broken handle, or a guitar may not stay in tune, a pipe can be drilled wrong or crappy briar. However, subtle differences in draft hole diameters and such is just a difference in what style the pipe requires to get a good smoke. It's a piece of briar with a hole in it. There's not a lot that can go wrong. And, when a pipemaker is asked about draft diameter verses length of pipe, I've found that they just use whatever drill bit they have. It's not exactly brainsurgery or rocketscience. And, making a pipe is not nearly as hard as making a guitar.
Maybe give the other pipe a chance and try to moderate your style to what the pipe might need to make it smoke well. Or, sell it, because there's always going to be someone who can make that pipe sing.
