I know the Shimano vs SRAM debate is long running but I have a slightly different question. I'm a "serious recreational" rider (and commuter) ready to step up from a Specialized Sequoia with a Sora drivetrain. I had never ridden SRAM but on paper thought I would like Double Tap (bikes in my price range are typically only Apex). However, after some test rides, I thought the new 105 was noticeably smoother and more precise shifting. However, I only rode one bike with SRAM at all.

Now I'm wondering if there is enough variation in adjustment that maybe it wasn't a fair comparison, and I should give SRAM another shot (fortunately I didn't get the wallet out just yet). So after a few rides, I perceived a major difference between SRAM and Shimano that maybe wasn't design related but adjustment?

I personally see a bigger difference in drivetrains than between bike models, once fit is dialed in, but that's just my novice observation.

Thoughts? Especially from those who have ridden both.
