Hand Made Shumrah is a CHUMRAH, The Machine Shamurah is more than fine, Alm ost No Posek is going to say you cant use it.
False. Some do not allow machine (I personally would eat certain brands).
And there is also no reason to eat Hand Shmurah the entire Peseach, you only need eat it for the Sedar.
False again. The Gr”a holds you’re mekayem a mitzvah by eating a k’zayis on any day of Pesach, and those who don’t consider machine matzo to be “l’shem matzas mitzvah” will be makpid on hand matzah for the entire Yom Tov..
You can eat regular Streits Matza for the rest of the Holidays.
Again, not true. Many are makpid on shmurah, and even more are makpid on 18 minute matzah (they stop the run and clean the machinery every 18 minutes), so your implication that they’re really the same is false.
