I don't use Dapps much beyond tinkering and learning how they work. Dapps are a Web3 remnant and quite honestly the ETH community's focus has shifted more towards DeFi "protocols". Protocols are the decentralized backend that anyone can build a Dapp on top of.
For example, Uniswap is a decentralized exchange (DEX) protocol and their Dapp is a pretty GUI built on top of the protocol. Synthetix is also picking up steam in ETH DEX trading.
Another popular protocol usecase is borrowing/lending of which Compound recently unseated Maker DAO, although they're quite different from one another. Maker built a Dapp called Oasis on the Maker protocol and Comound's Dapp is here.
A couple more protocols worth looking into are Balancer for rebalancing your portfolio and the Set Protocol which allows you to create an ETF like token from baskets of other tokens.
All of these guys built Dapps on their own protocol, but technically anyone could build a Dapp on their protocol. A popular trend is creating Dapps which aggregate/integrate multiple protocols like InstaDapp.
