i believe the OP was asking about clinical research versus bench/lab research, not clinical experience versus bench/lab research. it seems a lot of people don't understand what clinical research is. i think either is fine, depending on your interests. most md/phd programs are looking for more bench type research (since you'd be getting the phd in chemistry, physics, bio, etc) but top research med schools (ie harvard, chicago etc) i don't think care for regular md admissions. they just want to see some research experiences suggesting you may go into academic medicine and there a ton of clinical researchers in academic medicine. in fact, the nice thing about clinical research is you get to do research, publish,etc while at the same time getting a lot of patient interaction. i've done a little bench stuff but overwhelmingly have more experience in clinical research and its been great talking about it on interviews and just a great learning experience in general (in terms of research skills and patient interaction). hope that helps!
