will the answer to your question help you choose your future career or are you just wondering?

An interesting and commonly asked question. In general, they are both extremely competitive and attract different types.
However, numbers sometimes help, so let's look at some data:
From the last five years of the Dental Match (
http://www.natmatch.com/dentres/)
Note: The match rates below were calculated as the proportion of matched applicants over the total number of applicants submitting rank lists. This adjusts for the fact that some spots which go unmatched do so because the programs would rather not match an applicant than match an unqualified applicant. Also note that there are some ortho positions (e.g. UCLA) that are non-match. These are not included in this analysis.
OMFS
2006 59%
2007 54.2%
2008 52.9%
2009 54.5%
2010 53.2%
Ortho
2006 50.6%
2007 52.2%
2008 49.0%
2009 51.0%
2010 54.0%
As you can see, the match rates aren't largely divergent (in 2010, the match rates were nearly identical).
Bottom line: both are incredibly hard to match into, though your chances are slightly better than if you were just flipping a coin. They are also incredibly different residencies and careers in many significant ways. First, ortho residency is 60-80 hours a week, but a lot of that time is academic - reading, treatment planning, conferences. There are no ortho emergencies during the night that are actually seen by the orthodontist in the ED/hospital/office. Contrast this with OMFS, where the "lighter" weeks are usually 70-80 hours, but most residents work 80-100 hours. This does not include time for reading - it is expected that residents will read on their "free" time. Second, the personality type who goes into ortho, is, in general, different that than that goes into OMFS. Ortho types are very bright, motivated, hard-working individuals who either a) went into dental school already set on ortho, b) hated everything else in dentistry and defaulted to ortho or c) kicked a** in dental school, loved ortho and went for it. OMFSers tend to be similarly bright, motivated and hard-working individuals who either a) went into dental school already set on OMFS, b) hated everything else in dentistry and decided on OMFS because it's so different from everything else or c) kicked a** in dental school and wanted an a**-kicking back from residency.
