I got the LCR-22 partly because it was significantly cheaper than the J-frame .22 LRs, and seemed to be well made. I liked the use of appropriate materials for each section of the gun. Stainless steel, lightweight alloy, polymer, rubber. Still getting used to the funky trigger, but it's a good value for a DA .22 revolver.
The LCR in .38 Special however, is up against the 642/442 Smiths which cost the SAME or even a bit LESS than the Ruger, and the Smiths are a proven choice for carry. That's a whole new ball game, IMO. I think I would choose a no-lock Smith. I like the huge choice of J-frame aftermarket grips, for one thing.
