Windows batch if statement with user input

I am building a .bat that should compare user input with a value. It doesn't go inside the IF "%choice%"=="1" when i test it with an input of 1 or 2.

Here is the batch file :

    @echo off
    echo Enter '1' to blabla
    echo Enter '2' to blabla
    echo Enter anything to abort
    set /p choice="Type input: "
    IF "%choice%"=="1" (            
        echo toto1
        rem save into property file
        @echo currentMaster=%ecb%>> MDC.properties
        @echo masterDcName=ECBDC>> MDC.properties
        @echo currentClone=%bdf%>> MDC.properties
        @echo cloneDcName=BDFDC>> MDC.properties
    )
    IF "%choice%"=="1" (
    echo toto2
        rem save into property file
        @echo currentMaster=%bdf%>> MDC.properties
        @echo masterDcName=BDFDC>> MDC.properties
        @echo currentClone=%ecb%>> MDC.properties
        @echo cloneDcName=ECBDC>> MDC.properties
    )
    IF NOT "%choice%"=="1" (
    echo toto3
        IF NOT "%choice%"=="2" (
        echo toto4
            echo Unknown input ... Aborting script
            exit /b 400
        )
    )

The cmd output :

Enter '1' to blabla
Enter '2' to blabla
Enter anything to abort
Type input: 1
toto3
toto4
Unknown input ... Aborting script

Why is it not going inside the IF "%choice%"=="1" condition ?
