I feel your pain ;-)

To deal with the ISE<->Vivado speeds, we always chose a target which is
supported on both. One of the reasons, I have the artix7-100 on all my
boards, makes life much easier.
Then just use ISE for the "quick around" time, and vivado for the tough

Vivado was pretty much useless in the first revisions, but now it is at
a stage, where it is really usable. Yes, it is slow :(
On the other hand, the simulator in Vivado got much better, and works
for both, Verilog & VHDL, and also in mixed mode, which helps a lot.

And it is tough to complain about a free tool, which runs on Linux & Win ...

A lot of guys I know, use also GHDL for simulations, if command line is
your thing.
