I have different opinion about this matters. I would recommend CoinGecko instead, especially for newcomers.
Honestly, I tried to use Coingecko more for some other reasons, but CMC is still more user-friendly, or at least it is much more convenient for me to use.
Although lately, CMC has become quite slow, too much data is loaded, often completely unnecessary, plus various advertisements and javascript, and it has a lot of impact on the usefulness of the site itself.
I would like to see a better alternative that will be devoted exclusively to the needs of the user.
