Which do you prefer on a stock 170? Carter or Holley 1920?

I've got a stock 65 Valiant with a stock 1966 170. It had a 1962 Holley 1bbl on it when I got it. It does ok but the carb is needing to be replaced. What's the best running carb on one of these Slant Sixes the Holley 1920 or the Carter BBS? I'm not looking to try and gain HP but according to my 65 Plymouth Service catalog the 225HP Automatic non-a/c used a R-3058 with the 1 11/16 bore and flowed 235CFM. What about the Carter? What's it rating? Is it as easy to rebuild as the Holley 1920?
