I think it unfair to compare the jobs of a Queen Regnant with a Queen Consort.
A Queen Regnant is the Head of State, part of the political structure, has constitutional status etc and also do the duties that fall to a Queen Consort such as having babies and establishing a home.
Actually I feel the job of a Queen Regnant is much easier than the Queen Consort.
I have a few points here..
Things are set out for you already. Pretty much of the stuff is official business. And in that, more or less, one goes by the rule-book or as "advised". Sudden innovations and "out-of-the-way" modifications are hardly expected. And regarding the private stuff like running the estates, running the family, they can be delegated to husbands or managers. Public doesnt care much about them, unless something goes terribly wrong (rare).. And being a female monarch automatically gives you a soft-spot in people's hearts, you automatically have more charm and are more photographed, and finally, more popular..You have less competition among monarchs..
While being a Queen Consort is totally different. You dont have the "aura" of your own. You are seen as the wife of your husband first, and as Queen next. You always share the good/bad public persona of your husband.
There are always complaints that you are not doing enough. Because the lions share of your work--accompanying the King-- is not seen as work at all (Understandably, its the King's). So you are forced to go out of your way to find out "worthy causes" and slog on them. And how much ever you do, if anything goes wrong in the family or Household, you are the one to be blamed..something which Queen Regnants luckily escape..
And upon that, your position is not always secure..Overshadowed by Dowager Queens in early stage, and wives of CPs in later stage..
QRs are just measured in terms of "duty"..whereas QCs have several criteria..looks/fashon/jewels/family etc.etc..
But one lucky thing for QC I have observed is..they are almost unconditionally loved (with zero scrutiny) by the public, especially after they become Dowagers, and can almost retire. But QRs never escape scrutiny and "duty" till the end..
