Well, I don't use the latest, super fast FPGAs, I go for old 
standards that are cheap.
Right now, I have ise 13.4 installed on Linux, it seems to 
be stable, quite fast for the small FPGAs
I do, and doesn't complain about my coding style.  I use 
mostly Spartan 3 in the
XC3S50A(N)  sizes.  I've done some units with 32-bit 
counters running at 150 MHz with plenty
of margin left, that's fast enough for me.  I only use VHDL,
