Same here, but the 642 gets the nod 95% of the time. While I really like the way my baby Glock shoots as well--if not better--than its larger brethren, as others have stated it's really not much more trouble to step up to a G19.
As to the question regarding whether the 342 is worth the extra cost...as much as I'd love to say yes ( I'd *love* a good excuse to add one to my already substantial J-frame collection), for me the answer is "no."
