So I noticed my old TPlink 741n was dying, so I ordered a Xiaomi Mi router from aliexpress.

However TPlink 741n completely died on me fast, so i had to get another new one TPlink 841n because you know, that xiaomi might take forever to arrive.

Please take the time, if possible, to read the specs/features and help me on this:

Now my question is, since I have a cable connection of 1mbps, which of the two is better for me? What are the advantages that each can give me? Which one to keep and use?

As far as i can see, and know, both have dual antennas yet only the xiaomi has 5ghz support. Can this come handy?!

Thanks.
Correct me if I'm wrong but having a 5GHz option might help if you live in a crowded building where most or all 2.4GHz WLAN channels are in use.
@LifeEngineer

5GHz provides faster data rates at a shorter distance, whereas 2.4GHz offers coverage for farther distances, but may perform at slower speeds. Bluetooth and other wireless peripherals aren’t going to bother you in the 5GHz spectrum so there’s less interference. To get the best of both worlds, many recent 802.11ac routers have the capability for dual-band operation in both ranges simultaneously.
