Best advice I can give on choosing helmet is to look at this research: MIPS and Sliding Resistance of Bicycle Helmets
That’s basically all you need to know considering helmet safety before choosing one for yourself.
Second most important thing is fit. Try a few different makes on and see what’s comfortable, because if it isn’t comfortable then you won’t wear it and if you wear it it might not protect you as well as it could.
Talking about models comparison I’d recommend checking not the first reviews on the topic, but niche websites, like these:
