    Wanting to get rid of my Xfinity XB3 modem i "rent" from comcast for 13$ a month and replace it with a solid performer and am looking at these 3 viable choices. Can someone with more knowledge then me help me make up my mind for which is the better modem to go with. Hoping these have broadcom chipsets and NOT the puma BS!

    Motorola MB 8600 https://www.microcenter.com/product/481351/docsis-31-cable-modem

    Arris SB8200 https://www.microcenter.com/product/479580/sb8200-surfboard-docsis-31-cable-modem

    Netgear CM1000 https://www.microcenter.com/product/481225/cm1000-docsis-31-high-speed-cable-modem

    Which of those should I go with?! Thank you for your help

    We have all 3 of those - MB 8600 has ever so slight edge in design that provides slightly better throughput and 1 to 2ms lower latency (Comcast gig internet) - Google differences there's a couple of sites that talk about what they did slightly different with MB 8600.

    FWIW, if you have a Costco membership they have the Netgear CM1100 on sale for $120. Don't know how that unit stacks up against the others, however.

    Personally, I'm hoping the next round of DOCSIS 3.1 modems have NBase-T (2.5/5 Gb/s) ethernet ports. The link aggregation that some support is a bit of a kludge and won't help much when speeds surpass 1 Gb/s.

    With DOCSIS 3.1 able to hit 10G speeds I'd love to see 10G port (there are low-cost switch chips) - There's the talk of DOCSIS 4.0 coming in early to mid-2020 which may be higher speed ports to market.

    I have gig-cable currently - however it's not available in many markets (yet anyway), it is in part why there is such a slow push for better cable modems.

    I've trimmed 3 to 4ms out of my latency by going to all 10G network (with gig-cable and MB 8600 modem) - With my older age coming into play on FPS games, I'll take any edge (little or big) I can find these days lol...

    **Update** I took y'alls advice and did purchase the Motorola MB8600 modem. Got it in today and it immediately connected to my xfinity service with a DOCSIS 3.1 connection (YAY!!) and activated within 30seconds. My prior speeds using the XB3 modem was 452mb/s and now im getting 475-480+ mb/s. Nice little gain, and that is going thru my new R7000 Router. 9ms PING, and 480mb/s on a 400mb/s package... IM HAPPY! Nice to be on a DOCSIS 3.1 connection
