I just think it is insane not to do inpatient medicine in FP residency. But what you are probably referring to as that the 2nd and 3rd year DO residents do not do inpatient, since all FP DO residencies are linked to an osteopathic rotating internship. I think it all boils down to only a few major factors for me in selecting a residency.
1) I want to be around a lot of people who are intelligent and who are Americans. I have no beef with foreign people, as my family is from mixed culture. What I do not want though is to be an intern who works under many 3rd year FMG's (assuming the FMG's are the types that are very poor English speaking and had low board scores). I certainly recognize that there are many crappy US grads, and many good FMG's. Its just something to be aware of when you are looking at who your chiefs will be. You will never have this problem at one of the top 3 FP programs in the country and at any DO program.
2) Does the residency teach the skills I want to use when I am done. For me its quite easy, because I know I want to do OB, GI, Derm, and non-invasive cardiac procedures. I simply X them off my list if they cannot give me 40-50 c-sections in 3 years. Screw that fellowship crap when I can get it done somewhere in 3.
3) Location, Location, Location.
