Agreed.
I sold motorcycles for more than 10 years. Every day, someone would come in and say "my buddy says I should get a..."...and the "buddy" was totally wrong. 5'4", 110 lbs...on a 700 lb Street Glide? Um...no.
So, I would start at square one. "What kind of riding are you going to do?". "Solo or two-up?" And so on. Once we narrowed that down, and I'd sized up the person's physique, experience, and general coordination, we'd start looking at - and sitting on - actual motorcycles.
I'd save the buddy's choice for last.
Generally, all the "oooh, I like this" and "this fits me", were totally different bikes from what the buddy suggested.
I'd tell folks "sit on every bike you can find. Eventually one of them will grab you around the throat, shake you, and scream in your face 'I'M THE ONE FOR YOU!!!!!' - and I guarantee a) it'll be one you never expected, and b) it WON'T be the one your buddy suggested."
When I was shopping for my first EDC...I tried everything in the rental case. Twice. Got about halfway through the retail case, too. I shot well enough with the Shield. I hated the Glocks. I enjoyed the Sig...enjoyed the 1911s but a little big for me to realistically carry...but nothing grabbed me. Then, qualification day arrived for my CCW class, and I was (pardon the pun) under the gun to find something. I'd been researching, and was looking at the P365, and the XDs. They had 2 XDs's in the case - black, with the small backstrap installed, and gray with the large backstrap installed.
The gray one grabbed me by the throat and screamed at me, as soon as I picked it up.
They had some leftover 9mm rounds, so I loaded 5 (the last in the box). Target out to 7 yards. 5 rounds through 3 holes, all in a 1.5" group.
Sold.
Qualifications? 4 targets. 250, 248, 248, 250.
Been carrying it ever since, and love every bit of it. Discreet enough for my lanky ass to hide it...large enough for my big paws to keep a steady grip on it. On target fast, BACK on target fast.
Some folks may say "that's a cute gun for a big guy to carry". Some folks may say "only a 9mm?" Some folks may say "get a real gun".
To those, I say...let's go to the range, and I'll show you why I carry this one.
Carry what you shoot well, and screw everything else. When the chips are down and the SHTF, you don't need "image" and you don't need "status" - you need rounds on target. Period. Do what it takes to get that.
