Not always -- stubs made with higher Vf cables are longer, so in my 
experience they come out about the same for attenuation and bandwidth. 
The only way to get a deeper null (with the reduction in bandwidth you 
have noted), is to reduce the RF resistance -- this means larger 
diameter coax and a more robust shield, like hard line.
