I've yet to see anyone put forth a reason why more congresscritters would equal better government.
For better or worse, one of the jobs of a Representative is to provide constituent services, i.e., act as an ombudsman, for the people in their district. Hence, more Critters would mean fewer people per Critter.
It's generally the staff that handles these issues, not the Critter, though, and this could be solved by hiring more staff members to handle constituent services. The amount of attention constituents want or need, and the resources to respond to it at the other end of the phone from the congressmen, should be constant no matter how many reps there are.
Ultimately it is the “Critter” that represents the district, however. Having smaller constituencies would increase the chance of a legislator being able to cast his or her vote on the floor of the House secure in the knowledge that his or her vote is representative of the district to which he or she has been elected, whereas in larger districts voters from different areas often have conflicting interests.
