You are experiencing the long proven Kimber 50 / 50 concept - half of them decent, half of them crap.
Don't sugar coat it.
Kimber released their revolver in 2016, so they're still pretty new to the wheelgun design. Jumping into the aluminum-framed end of the pool might give them some new challenges. They're still really new to the revolver world.
Colt returning to the revolver market gave them some teething pains to address. I'd not be inclined to jump on them until they've proven themselves and their new manufacturing methods and new revolvers.
Taurus has their new Executive Grade, made in the USA, and while the thought of them claiming they're 'higher end' revolvers is intriguing, I wouldn't jump on one quite yet. I have too many proven S&W's that do the job, and an older Ruger Service-Six (MagNaPort tuned).
Some folks like to be the first on their block to jump on each new thing that comes along. Their prerogative. Somebody's gotta keep all the gun companies in business.

Nowadays I only carry revolvers for retirement CCW/self defense. I want to give myself every possible advantage. Hell, that was the primary reason I pushed to be sent to a S&W revolver armorer class, so I could inspect, maintain, service or repair my own guns.
I missed the chance to go to one of the older LE/Mil Ruger revolver armorer classes, which I was told by Ruger were stopped when someone retired. At least they're known for being parts-is-parts revolvers, meaning no hand-fitting. Bummer the Security/Service/Speed-Six parts are no longer supported, though. I sometimes miss my SP101DAO, but it went to a very good home where it's often used for feral animal defense in AZ.
