Shifter question - Zipp R2C vs SRAM R2C

I would like to get some opinions from those that have used both the Zipp and the SRAM R2C shifters. I guess it’s a pretty simple question, which do you like better? I am planning on upgrading my cockpit to Zipp carbon so figured it would be a good time to upgrade my SRAM 500 tt shifters as well.

For what it is worth, I tried the search but didn’t have any luck.

I think the Zipps feel alot better in your hand. People have had shifting issues with them but I haven’t. Putting up a gently used pair of Zipp R2C for SRAM in the classifieds once I’m done being lazy…
