The 200 series of Merkel guns included several models, ranging from essentially an entry level 200 model, to an exceptionally nice 203 and 204 model gun. Most of the Daly imports from the 30's were very nice guns as well, from several different makers, including several models from Sauer during that late period. I have not seen the upper end guns from Defourney, but I know they are out there, they were a respected maker. I would think the "typical" Merkel or the "typical" Daly import from the period you describe would be better guns than the "typical" Defourney from the period, but that is not meant to say Defourney did not have some higher grade guns during the period.
