You are wrong, trustwallet has same feature as metamask, you can also add new network or new token right on trustwallet wallet. Now, I no longer use trustwallet on my phone so I cant guide you, but I remember exactly I used to use trustwallet to add new tokens. But if you often use your computer to work, then metamask is a better choice as it has both browser and mobile versions. As FatFork said, you should edit the title accordingly.
