You didn't say what version you are using nor did you show what output you get. As for me,
In[1]:=
$Version
Out[1]=
"5.2 for Mac OS X (June 20, 2005)"
In[2]:=
Integrate[Max[x, y], {x, 0, 1}, {y, 0, 1}]
Out[2]=
2/3
In[3]:=
NIntegrate[Max[x, y], {x, 0, 1}, {y, 0, 1}]
Out[3]=
0.6666666666666666
These are clearly consistent
