Toto Toilet choice - help please

[Zelda]

Hello all, and thank you for sharing your experiences and knowledge!

About to do a primary bath remodel and have been searching for the toilet.

I have narrowed it down to the Toto toilet, and these two models:
CST776CEFG or CST776CSFG [I realize that the seat is purchased separately]
---or ---
MS776124CEFG or MS776124CSFG [comes with the seat]

Here are my questions:
1. What is the difference between the CST and MS?
2. Which one is quieter --- E (1.28) or S (1.6)? [the toilet wall backs up to the bedroom, so this is important]
3. Other thoughts on the 1.28 versus 1.6 size?

Thank you again for your help!

E = 1.28 GPF
S = 1.60 GPF

CST means you need to add the seat
MW has the seat in the box with the bowl.

These are all pretty quiet, I have something similar in my Master bathroom.

Thanks so much!

Any preference 1.28 vs 1.6 ... And ... does 1.28/1.6 affect the performance and/or how quiet it is?

I think the 1.28 is a little quieter. It does use less water. It's what we use on the West Coast now.
