For DIY, is there a big difference between Senville and Mr Cool ? Especially in colder climates (High desert southwest lows of -5 deg)

Hello, i've been looking into installing my own mini splits for a bit. i've helped install them before so not too worried about that, just trying to find the best option. Main thing im worried about is heating, as where i live temps are fairly cold in the winter (standard is like 10F to 30F, but there are outlier days hovering around zero).

Ive heard of hyper heat models, and not sure if that's necessary for me, but have been looking at Senville and Mr cool and was wondering if anyone has any preference or insight on if their diy models would work in lower temps.

Thank you
