I'm not saying gear doesn't matter, I am saying specific gear (probably) doesn't matter. If you pick the Sigma 17-50 or the Canon 17-55, doesn't matter much.
Agreed, the differences between two similar lenses made by different manufacturers will generally not show significantly, unless there is a significant quality difference, or a difference in max aperture.

Say you were trying to decide 135L or a 70-200 f2.8. Would your pictures be that different if you'd picked the zoom? You might work slightly differently, but you'd be taking essentially the same images.
Hmmm, I don't agree here I'm afraid. The pictures are going to be different sometimes. Sure, if you are shooting at f/8 and around 135mm then the images are going to be essentially the same. However, the lenses are actually very different. The prime allows you to shoot at f/2 which is better at throwing the background totally out of focus, the zoom won't be able to give such a nice background. It is better at that particular job.
On the other hand, the zoom is much more versatile and allows you to shoot at the distance which gives you the best perspective, and arrangement of the elements in the scene, whilst still filling the frame with the subject. The prime means that you either stand back and crop a significant amount of the frame away (compared to shooting at 200mm, say) and keep your chosen perspective, or fill the frame by moving forward but lose the perspective that you wanted. Obviously, compared to shooting at less than 135mm, you have no option but to stand further back in order to get the scene in, but the perspective is forced upon you and may not be what you want.
Changes of perspective significantly alter an image, so no, they won't be "essentially the same".
As JeffreyG mentioned about switching from a 300 prime to a 100-400L, a prime in the middle of a zoom range does not mean that it can do the job of the zoom. I also have the 100-400L and a 300 prime (the f/2.8) and they are used in totally different situations. Sure they can be pretty similar at 300mm and f/8, but they are hugely different otherwise for the reasons I gave above, and for the reasons that JeffreyG gave. I also have a 70-200 f/2.8 which is almost covered (focal length wise) by the 100-400L, but again has it's own niche where it gets used because the 100-400L isn't suitable (and vice versa).
Of course, gear is important in that you cannot capture an image with unsuitable equipment for the task at hand. However, the most important factor is the photographer. Without the ability to visualise how they want the finished image to look, or the best perspective to use, they will never get the best out of it.
So, yes, I do echo the sentiment that the important thing is to get out and shoot, and practice. Constantly obsessing over gear is a waste of time, but you do need to think about your needs, and get the right tools for what you want to do.
