What is the difference using plastic or bronze mould for pasta maker?

I want to understand the difference in using plastic or bronze mould for my Philips 200W pasta maker.

There is option to get a bronze or plastic mould for my machine. I have read the bronze will give more texture so that the pasta can absorb the sauce better.

I am wondering: is the difference so significant? When using a hand wound pasta machine I remember the pasta being good enough and taking on the sauce well enough. Further the bronze can only be cleaned by hand.
