Any modem needs the latest DOCSIS which is ostensibly a standard but in practice is a big opaque proprietary blob afacit more or less shared among telecoms that adhere to the "standard". Using an older DOCSIS or one without the Comcast's latest-greatest enhancements (hence the quotes around "standard") will absolutely sacrifice line quality.

Moreover Comcast gives you their latest-best modem for negotiation with their upstream WAN and replaces it when it ages out or gets recalled. With bridge mode enabled, it's as close to a dumb pipe as you're going to get without sacrificing quality.

I would much rather make that sacrifice than trust Comcast everyday of the week. Not disputing you at all but I don’t trust a thing about that company an never will

Edit: and I should add, I haven’t personally noticed any difference in quality
