To the OP,
Here are roughly comparable examples from each, a Bullnose from Ingram, and a Model 60 from Winston, both in Ivory micarta and D2.
The Ingram is very thin, the Winston is fuller in the hand, but that is a difference that either could alter based on the design chosen.
Measured at the choil, the Ingram is 0.125" and the Winston is 0.155".
The steel seems to work equally well between the two on cull deer and feral pigs from use last season, and there is not a difference between them in edge retention comparing identical steels.
Either should serve you well.
