I'm the hockey skate bro that posted many days ago
The hockey boots are laces only, which offers you a lot of control over how tight you want it where you want it (from the ankle down). All the hockey skates I've worn flare out above the ankle and its really hard to tighten the boot above the ankle. it offers a lot less support above the ankle which is great for maneuverability because it lets you bend at the ankle, but not so great for beginners because they will have weaker ankles and collapse on the inner edge. Also if you skate extreme long distances you'll find that as you get more tired its harder to keep your ankle supported with muscles and the hockey boots become less and less comfortable. Muscle training can negate this completely; marathon and race skates are all very low cut boots and they don't seem to have any issue with it.
If you're into slolam style skating you might like the hockey boot feel. one thing to consider is the tendon guard hockey skates have, which can make it difficult to point your toe.
The HiLo setup many hockey skates advertise is not actually a rocker at all. on my skates it means the two rear wheels are 80mm, the two front wheels are 76mm. if you have brand new unworn wheels they sit perfectly flat without rocker. it does mean that the frame and boot allow you more of a forward lean, much like 165 mount Seba and other slalom skates use. The foreward lean is supposed to help with explosive acceleration and it makes sliding/ stopping easier too.
Whenever I switch from my hockey skates to a UFS boot and frame its always very awkward because it feels like I'm forced to lean back
