I noted 2578lf-mpu comes with metalic pop-up and 2578lf-278 with plastic, whic is more durable and/or sturdy
Thank you for your inquiry. The difference between the Delta Leland lavatory faucets 2578LF-MPU and 2578LF-278, is the Pop-Up assemblies that come with them. The model 2578LF-MPU comes with a all metal Pop-Up and the 2578LF-278 model comes with a 50/50 Pop-Up assembly. The faucets and drain assemblies would have the same quality, it would be a personal preference for what is best for your sink installation.
