That could be debatable, at this moment in time.
I did buy 1500 shares on margin at $2.75 last week
and 1000 warrants with cash.
My margin shares are underwater and I would have to sell for a loss
My warrants are up $0.25 so I could sell for a gain.
If the pps dropped even lower, my margin loss would grow bigger whereas my warrant risk will always be the same.

But yes, in the long run you could make more with the margin shares
because I have to wait until $4.04 to convert warrants to break even
whereas with the $2.75 shars I would be up $1.29 at $4.04

Don't play warrants or margin unless you can afford the RISK.
