I appreciate all of the comments.
There are situations where the different points of view can lead to an acrimonious conversation.
My FiL and I are shooting buddies. We have both been hearing for years how great the CZ75's are. I finally lucked onto one. It was actually an EAA "clone" that I got as surplus for cheap (those last two words should not have surprised you). It had been used for military training and/or a shooting club gun and looked like a LOT of rounds had been fired through it. But it has a great trigger, nice sights, is accurate, reliable, and fits our XL hands well. So my FiL decided to buy one for himself (yeah, sometimes my purchases end up being "guinea pig" purchases for his). He is not a cheapskate like I am, and decided to buy a real CZ75 NiB. He got a good deal on it, but it obviously cost substantially more than my surplus clone. He took it to the range with us on our next outing and asked that I bring mine as well. He shot a few boxes of ammo through his, and I tried it too. He also shot a couple of magazines through mine. The problem was that mine obviously shot better. It has better trigger, seems more accurate, and fits our hands better (apparently the EAA is a little larger than the CZ). Being who he is, he just stated the obvious, added a few choice words for emphasis, shrugged his shoulders, and went on with his shooting. I later mentioned that his would undoubtedly wear in some, he would get used to it, and eventually it would probably shoot better than mine. He gave me his "I know you are just BSing me with your danged optimism" look, smiled, and shrugged again.
But some people in that situation could have gotten embroiled in an argument. Someone in my shoes might have mocked his purchase and belittled him for wasting money. Someone in his shoes might have gone the angry denial route and started going on about how much of a piece of junk my EAA was, just because of hurt feelings. We are not those kinds of people, but it could happen.
Or it could be the opposite situation. A year or two ago we were both looking for "pocket nines". Being me, I found a used LC9 for cheap because everyone wanted the newer LC9s version. It works fine, but the trigger isn't great and it doesn't fit my hand that well. Being him, my FiL worked on finding the best pistol for his needs (as long as it didn't cost a fortune, he is not on the far end of the "grail gun" spectrum). He bought a brand-new SiG. I think it is the 250 model. It is a very nice pistol. I have not compared them or shot them side-by-side, and they might not fall into the exact same category, but his seems to be obviously the better pistol as far as trigger, ergonomics, nd accuracy go. I could have gotten all huffy and tried to claim that mine was just as good, or that he was crazy for spending too much money, or whatever, but I just complimented him on the nice pistol. And he could have told me that I was an idiot for going the cheap route and getting an inferior product, but when he shot it he smiled and said it worked just fine.
I am glad that I never get embroiled in those kinds of arguments with people like my FiL and cousin who are more towards the opposite end of the spectrum from me, but it's easy to see how it happens.
(I wasn't done with this post, but had to stop what I was doing for a while and come back to it. I just posted what I had and came back to edit/finish it, so this version is significantly different.)
