Thicker
paper         100-250 gsm                Thinner paper                  45-90 gsm
The paper use more ink   
 | 
  
The paper use less ink 
 | 
 
Front and back are the same on
  most thicker paper  
 | 
  
Front and back are seldom the
  same; you can not use the back 
 | 
 
Large value change, especially on
  dark and dull colors 
 | 
  
Value change but not as much (dark
  colors looks darker on thin paper) 
 | 
 
The time it takes for the ink to
  dry is normally quicker  
 | 
  
The ink stays wheat longer
  (allowing you to blend wet in wet) 
 | 
 
Easier to layer more (there is no
  problem to layer).  I have never
  experience the ink staying on the surface and creating puddle.  
 | 
  
Will not take as many layers (to
  many layers will create problems). If you put down a lot of ink you may end
  up with a puddle. 
 | 
 
Feathering and bleeding is less
  common on thicker paper 
 | 
  
Feathering and bleeding occur more 
 | 
 
Bleeds normally through to the
  next page 
 | 
  
Are more often bleed proof; that
  is, it doesn´t bleed through to the next page 
 | 
 
Colors can look milky on thicker
  paper  
 | 
  
Very rare that colors look milky
  on thinner paper 
 | 
 
I also found that if you work on a thin paper you might want to work fast, because your ink can create lines that are difficult to cover up when the ink has dried. On thicker paper however, it isn´t as sharp lines so you can take your time, and if you want, stop the drawing and continue later on.
