synthesis tools

Hi everybody,
I would like to obtain people's opinion on the use of different
synthesis tools to target FPGA designs. I am thinking of tools from
Synopsys, Mentor graphics and synplicity. If there are others, I would
like to know. These are excellent for targetting ASIC designs where
every little space and power dissipation is critical. My question is,
is it worth using these expensive tools when there are also synthesis
tools created by the manufacturers of the FPGAs such as xilinx ISE
which is free.(I use xilinx exclusively. Sorry to the Altera fans out
there). Secondly are the first tools much much more efficient than the
ones xilinx offers such that the gain obtained from them offsets the
cost of the tool. Thirdly which one is better for Xilinx FPGAs. Thanks
a lot for your time,
Amish
