Having actually owned both, the LCR has a better out of the box trigger and a 2 finger Tamer grip that is compact and works extremely well. It's also very light and has an easily replaced front sight if someone wants something different.
The 638 and 642 I owned were nice, but I never looked back after owning an LCR. Life's too short having a gun that doesn't shoot as well as a well made gun that's lighter, cheaper and has less recoil. My brand new 2014 LCR cost me $360 shipped total. The biggest plus was my FFL didn't charge me anything for the transfer.

Now I did have an older Talo Navy LCR a few years ago, but I stupidly sold it to put towards another purchase. I'm kind of glad I did though since they're now making them without locks under the grips. My Talo had one, my new one does not due to customer complaints according to a Ruger rep. I wonder when S&W will figure that one out.
I don't mind the look of the LCR. I think it has a "futuristic" look to it and actually like it. Thing is, it's a defensive firearm. Either way if I can shoot the gun well and it's reliable, I don't care what it looks like. The bad guy
really isn't going to care what it looks like. I don't think he'll look at it pointing at him and go "Wow, that's an ugly gun. I now have all the confidence that I'm completely safe since ugly guns are worthless. Good thing you didn't have a J Frame or I'd be wetting my pants and laying on the ground in the fetal position"
