USD dividends in non retirement account

As part of a past employers ESPP/Bonus stock program, I've got some shares of a US Stock in a brokerage account tied to that past employer. The stock does pay a regular quarterly dividend but I can't really do anything with it in that account. Because it's tied to the employer through a group plan it doesn't cost me anything to leave my shares there(just a standard transaction fee if i sell those shares), but i also can't setup a drip or buy any other shares with those dividends(in that account).

I've got my primary RRSP/TFSA's in Questrade and was considering just wire transferring the US cash from my dividends to one of my Questrade accounts as USD and then i could purchase some US based ETFs/stocks in questrade with it quarterly.

First off, which would be better for this from a tax perspective? Transfer to the RRSP account or the TFSA account?

Second, any other options to better manage this money? It's not much, couple hundred a quarter. It'll cost me $10 to wire it to questrade.
