The primary use for the Taurus, especially shorter barrelled versions, is for carry, either open or concealed. It's fairly small and light but packs a good punch. It's also suitable as a home defense gun. I haven't shot it, but I've heard it shoots well, with possibly a rather rough and heavy trigger pull, especially double action. The S&W 625, on the other hand, is a big, heavy, gun. It can be carried, but concealed is a tad more difficult than with the Taurus. It, too, is great for home defense. What it's got is great sights and a great trigger, both in single and double action. It's heavy and stable, too. These qualities make it more suitable, IMHO, for the purpose you specified, i.e., range shooting. I love mine for these reasons. Quality is as good as it gets. So, based on what you've told us, I'd save up and buy the 625. You won't be disappointed.
