You can access the respective shots at different apertures via the links beneath the main image. All shots with the 1.

The image is still usable but you can easily see how much sharper the shot at f8. Stopping down to f8 did not improve the image quality by much so you can shoot wide open and enjoy the benefit of a shorter shutter speed.

I say meh to the avoiding teleconverters. I use my 2x all the time with my sigma and I sometimes even toss in an extension tube. This setup allows me to remove two big lenses mm and mm macro from my bag and still capture amazing photos. I've used pretty much all of these lenses at one time or another. I can tell the difference in actual real world pictures taken with the Tamron mm and the Canon mm at a glance.
Maybe the reason you don't mind putting the 2X on your Sigma is because it isn't very sharp at mm to begin with.
