I really feel for you! Only two handguns?!?! I don't know what I'd do!!!!
Either one is going to be a good choice. I personally have a fondness for the longer barrels. Some have a much better case color pattern than others- so that may have some bearing on which one you might like. Check out the actions- each one can have it's own little differences- especially on used ones that may have had some gunsmithing done to them.
The good thing is, I'm certain that .38 special and .357 magnum will be much easier and cheaper to get, and much easier to start reloading for if you decide to- if you aren't reloading already.
