I don't think it's a question of which is generally a better bullet, but which works most accurately in your guns. I've always had great results from my Lyman 2-cavity block, but I also know others who will swear by their RCBS moulds. Unfortunately one won't know which is "better" until they've bought and used both.

These moulds aren't as similar as you might think. I have both and using the same alloy the Lyman weighs only 240-241 grains to the RCBS 255+.

Meplats are close but the RCBS looks bigger.  I greatly prefer the RCBS mould.

Lyman drives me nuts! They have cancelled most of their best moulds. (454424, 452649GC etc)

PS the RCBS 270 SAA is a gem of a bullet mould

I've used the RCBS and the Lyman molds. They both are great products and throw a nice bullet, but both have one major problem, from my experience. They are set up to throw a .452 bullets. My three 45 Colts and the three 45 Colts my shooting buddy has lead like crazy with them. Once I found an old 4 cavity mold, by Lyman, at a gun show, that throws a 255 grain .454 full wadcutter my leading problem was ended. All I did was use the same powder charge and seated the wadcutter deeper into the case.
I have since purchased two 4 cavity molds from Saeco, that throw a .454, 255 grain SWC. I have no leading problems and accuracy is great!
That old full wadcutter mold is also being used to make some gilt edge plinking loads. This bullet looks a beer can with a roundish dome on it.
My advice is stick with .454 molds in your 45 Colt and lessen your frustration.
