I has a little more gain in the direction directly opposite the 
direction the top wire is running away from the vertical wire (maybe 2 
dB or so).  The angle created by bending a wire causes some field 
cancellation in the direction of that angle, so less gain in that 
direction. 

That assumes the L is close to 1/4 wavelength long.  If it is longer, 
then the answer may change because the total gain is the sum of both the 
vertical and horizontal components and on the higher bands, the top part 
radiates more.
