Depends on the models.
Maybe it's because I was brought up on wargaming when every model was lead it doesn't bother me. I'm still trying to get my head around plastic. It's terrible stuff plastic you know. It has a lot lower melting temperature than lead.
Only thing I like about plastic and finecast is that the paint doesn't chip if you drop it. So depending on the models that are released I'd buy it if I wanted to update something.
Ideally everything would be plastic - but meh, I disagreed with people saying that 20 years ago, I can't change that now
