For Comcast 105Mb, keep Arris cm820 or get Moto SB6141 or other?

Hi!
So I have this Arris modem from my other home so since its a different city I need to return it but by mistake (my wife didnt know), Comcast used this modem when setting up my service.
They just upgraded the speeds also to 105Mb and Speedtest just showed me at 93.67/12.22
So, I can either get a used CM820 from Ebay to send it back to my previous ISP and keep the same CM820 I already have running...or a local is selling for example the Moto SB6141 for $40 dollars.
I think I am pretty much maxing out my speeds unless you think I can do any better with the Moto at all.
Just trying to figure out which way to go.
Here is my stats screenshot just in case.


Thanks for helping!

Both will perform the same.

yea shouldn't matter, for Suddenlink 107Mb I have a Motorola SB 6121 and it runs just fine.

btw Ehren is there a story behind your custom title?

Both should be fine. I'm currently using SB 6141 on 105 and not seeing any sort of impact/degradation.

Thanks guys!
