Toto Drake II (ST454E): Fluidmaster 400AH or Korky 528MP Fill Valve?

[Rdonchez]

The fill valve died in my Drake II (non-korky style). I was wondering which is the better fill valve between the Fluidmaster 400AH (Performax) and the Korky 528MP? Do both work with this toilet? Any pros/cons? Looking online seems both are well reviewed - maybe a little higher for Fluidmaster.

Thanks.

I have used both, and either one would work fine on that. The Fluidmaster is a little easier to adjust.
The blue cap Korky for TOTO has specs for adjusting for their different models.

Is there any difference between the internal float of Korky v external of fluidmaster? Or both about same in terms of reliability?

Fluidmaster is pretty durable, though it's pretty close.

Both of those have replaceable seals...in some ways, the Fluidmaster might be a little easier to replace, but neither is hard.
