I have had 105 2x and its great, cheap, reliable and durable, no issues at all, I have SRAM force etap 2x12 and its just awesome, and I HAVE sram apex 1x11 on my gravel bike and i really like it. I don't see a huge jump in quality from one to the other, but I do like srams mechanical shifting style a little bit more but both are pretty awesome, in my opinion.
