Oh yes, I see what you mean.
Plastic no good to horse up against a fibre washer.

I can vouch for the quality and reliability of John Guest fittings. I use them in the training workshop that I run. I use the JG fittings because they are demountable without tools, I can reuse them so many times which saves on my course budget. It's easy to replace individual parts in them. Most importantly I have had the same JG pushfit elbow on my pressure tester since this time last year. It gets mounted, pressure tested and demounted and reused many times a week and has not failed me yet. Although I will use copper wherever possible and don't like plastic in general I do trust the JG range.
