Need new modem: Netgear CM2050V vs Motorola MT7711

I have an older Netgear modem that has reached its end-of-life. (I was notified by Netgear.) They recommend I replace it with their CMV2050V. I don't know if I need one this expensive. Would the Motorola MT7711 work as well for me? I do need the voice connection. My plan says my download speed is up to 400 Mbps and upload speed is 35 Mbps. Xfinity also recommends the Netgear one saying it is for next-gen speed tier. Both of these are at least 5 years old so if they are going to reach their end of lives too I'd rather not spend a lot on one. Thank you.
