Ruger is infamous for under sized or over sized 45 throats.
It is, on the internet. I don't recall hearing or reading about Ruger having that problem before the Internet age. Maybe they didn't have the problem back then?? I got my first Ruger .45 in 83. I've had 8 Ruger .45s since then, Blackhawks, Vaqueros and New Vaquero, never had any issues with any of them. Never even thought to check the chamber throats until I read some crap about them on the Internet, and then, decided not to bother since my guns shot fine the way they were.
Did do a bit of "research" and found some people who had been gunsmiths /shop owners back in the day, and heard from them that Colt had chamber mouth issues in (some of) their SAA .45s when they resumed production after WWII and it continued for a while in the 50s.
Seems that back then, when there was an issue, the usual thing wasn't to ream the cylinder, but to shoot differently sized bullets. A typical example, was a guy bringing in a gun that wouldn't shoot well (shooting .452" bullets) and the smith telling him to shoot .454" and the gun turning out to be quite accurate with them. Different times it seems....
As to my personal opinion, a stainless Vaquero is plain ugly.
Your personal opinion is as valid for you as mine is for me, and the next guy's for him. Some folks value looks more than others, some value feel, and some value performance most.
Some folks even go by just the price. I reckon that's why we own different guns, drive different cars, eat different foods and marry different women...
Personally I don't mind stainless or nickel finished guns, but I'm not crazy about them. Nor am I the traditionalist who thinks case colors and wood grips are requirements for my SA revolvers. Don't mind having them, not paying extra to get them. Plain blue is good enough for me, I don't even care for high polish. But, that's just me. Other people like other things and I'm glad we have so many options available.
Just because they are choices I wouldn't make doesn't mean they're wrong choices for someone else. Unless, of course, they turn out to be...
Fellow I knew got a Ruger .44 Magnum SA at a gun show, gun was "pretty", and had been extensively reworked by someone who had skill, the work was well done. Barrel & rod shortened considerable, fitted with a birds head grip frame. Nice looking black wood stocks.
My friend had very short thumbs and was convinced he needed the hammer spur moved, modified the grip frame to take the Bisley hammer.
Gun looked nice. But I didn't think it a practical .44 Mag. My friend hit me up for some ammo, the lightest stuff I had was 240 SWC over 10gr Unique. Gave him a box.
Week later he tells me how much pain he got shooting that gun, and swore he's NEVER putting magnum ammo in it!! I suggested trying .44 Special. He moved away shortly afterwards, never found out if .44 Specials did it for him, or not.
Point here, guy got the gun on its looks, and learned its performance was simply something he couldn't manage. Everybody's different.
