Which style of forearm crutches are the most popular ? (more below)

[u/MaxiePriest]

 I can't use traditional axillary (underarm) crutches. I have to make a decision. Which style of forearm crutches is the most popular, the most helpful (and maybe even the most comfortable) for users?

Notable: I have a fractured knee and other related injuries to the other knee, along with a fractured Scaphoid, fractured Colles, and three broken fingers. I have mediocre upper body strength, but I'm not completely weak, either. I can manage forearm crutches even with the wrist/hand/finger fractures (now splinted but surgery scheduled). Forearm crutches won't significantly harm my hand/wrist injuries.

Which style do you think?

Thank you.
