I’m a fan of Shimano for beginners as there’s a bit of float (enough anyway)
& really like the adjustable tension for people who aren’t the most confident, meaning they can set them as loose as they like until they get used to being clipped in, then up the tension to increase the security.
Others disagree, but that’s my thoughts.
Oh, avoid the multi release cleats, you will pull out of them when you least want to!
