The last time I had Comcast was 2016. I did not have a bandwidth cap and they had only just instituted it in a few test markets.

Now it is nation-wide.

I get slightly more speed than I did back then, but I'd trade that extra speed for no bandwidth cap in a heartbeat. Obviously usage depends on person and plenty of people won't notice cap but I can easily drop 1/10th of my monthly bandwidth budget on a single game on steam these days.
