Nanominer vs T-Rex Miner

New miner here. Just scratching the surface. I started with Minerstat on Windows 10 which set my pool to Nanominer.

After swapping to HiveOS I now have the option to use T-Rex miner which is something I’ve seen a lot of on YouTube.

My question is, what’s the difference?

Currently just using an old HP Laptop with a 4GB GTX 1050 in it whilst I wait for hardware to arrive so I’m doing as much research as I can.

Thanks in advance.
