Most have my rant on this.

There is no reason not to have both or more.
All is in the data folder.
When you install and patch SH3 to 1.4 simply make a complete copy of the data folder to an outside the game folder, called it 1.4stock.
With that safely tucked away install GW. Once installed, make a copy of the entire data folder and place that in that outside folder call it; GW, duh!!!

Now, delete the entire data folder in the SH3 game folder directory. Copy and paste the entire 1,4stock data folder back into the game directory.

Now install NYGM.
Make a copy of that complete data folder to that outside the game folder and call it. You guessed it, NYGM.

So you have all three saved and can move them back and forth as you choose (It is a big folder so takes a few minutes each time).

With all this great stuff saved one can now tear through whatever is in the game data folder edit tweak try anything new you may be curious about and if you screw up, you simply go to the saved data folder and put back the original files or delete the whole thing and copy the entire data folder again.

Personally I installed GW and then ripped it up adding things from other mods and making many tweaks myself.
HDs have gotten so cheap there is no excuse not to have all this stuff tucked away.
