Not a good choice because Apollo can pull 200w while Compac F is around 9w. So Apollo consumes more power than the USB stick not a good choice for a 9 cents rate unless he doesn't care about the power consumption.
For clarification, if you have 10 Compac F you can also get 3th/s with around 90w which consumes less power than Apollo.
I just want to add this calculator below with a breakeven analysis to estimate the ROI of your unit.

Those are operational costs, buying an Apollo would be much cheaper and simpler to run than 10 Compac Fs.
You can in theory(it's sold out) buy 3 Compac Fs for $699.99
Note that individual Compac Fs are being sold right now at $359.90 and to be able to get 300GH/s you also need to buy special rare USB hubs that provide at least 2.4A per port, a power supply for each hub, and fans.
But let's assume an individual price of $233.33 based on only buying those packs of 3 miners. That means to get 10 Compac Fs you will need to pay about $2.3k.
In comparison, one Apollo BTC costs $499.90:
Also, it's hard to make a fair comparison because you can change the power settings on both devices.
These are real numbers that I've measured myself:
For the Compac F, to be able to run at 300GH/s you need to provide 2.4A in the USB port. At 5V that's 12W.
The Apollo can run at different power settings, I'm running mine in a silent setting, so it's producing about 2.1TH/s at 120W.
That's exactly 7 Compac F to match the hash rate of the Apollo.
It's still cheaper and simpler per TH/s to get the Apollo:
1 Apollo BTC: $499.99
7 Compac F: $1,633.31
You can buy 3 Apollos for that price!
