Hi Terr
I just installed some subway tile with the bevel couple weeks ago and I really like it. Makes the rest look so plain, tile I installed was by Adex. I had previously installed their subway tile with crackle finish a couple times. It did not take away from the countertops though I didn't feel these c/tops were busy.
I did do an accent area at the sink but not the stove. I don't feel you would need any accents. Not sure what you mean by not needing spacers you do need to space it. I used 1/16" never butt them up against each other unless they would have nubs built into the tile sides providing spacing.
Some pics of the one I just did with the beveled tile. The customer looked a long time for something for the backsplash and when she found these the search was over
