Let me try and simplify this for you.
I had a ceramic travel mug and a stainless one. I rarely took the ceramic one out of the house because it was more fragile. The one god damn day I took it out to the barn, it fell over and broke. I was devastated. Thankfully it wasn't one of those commie holiday Starbucks ones, rather just a generic Starbucks one. One of those travel mugs was meant for me bee bopping around the house and morning runs to Whole Foods just after the yoga classes all let out. The other is meant for my training days/weeks, in the barn, etc. - where I don't have to worry if I drop it and slap it around a little. They both do the exact same thing - hold my lovingly created mochas and keep it warm for a little while.
The SnowPeak gear is nice, pretty and thoughtfully designed and built by Japanese people with a rich history of unisex clothing. The Partner Steel stoves are designed and built with a different mindset by men wearing plaid in Idaho - to be extremely durable and well built. To withstand years and years of use and abuse. Not gingerly placed in the back of fine British vehicle with a Kimono draped over it. These are outdoor camp stoves, not your beloved case of South African or Chilean artisanal wine.
In other words, I just wanted a better built (you say overbuilt, but that's fine) camp stove that I'd have for a lifetime, made by some dudes in Idaho that make just stoves - not unisex robes, man purses and sake cups. Now remember - that stainless coffee mug I have here in my house IS overbuilt for sitting on my couch and the cupholder in the Tahoe. But not when I venture outside to the mean streets of Middleburg, the barn, work and a place for my Yeti decal to reside.
I understand the desire to defend your purchase. SnowPeak is a little embarrassing though. Not unlike owning an alpaca cardigan from Barney's.
