Can I use this or Hard as Nails?

I preferred this as I have both. My nails are super thin and brittle and Diamond is harder than the Hard as Nails. And it takes less product of this than Hard as Nails because the second is thicker more polish likw. This is more liquid and quicker to dry completely

can I use this over gel nail polish

Yes you can, but for it to work (strengthen the nail) it should be used directly on the nail

How does this compare to the sally hansen mega strength hardener?

hardener worked for a while and not so muchy. try both

i have a split that grows out lengthwise and wont let me play guitar the way i want. Can this help?

You won't know until you try it, but my guess is, it would help if you kept the nail trimmed.
