I have used IDEX, Binance DEX and Uniswap and from my experience, Uniswap flourishes in areas where other DEXs are found lacking. At the moment, It has the highest number of active users and volume to to its feature that allow users to provide liquidity while earning a part of the fees. I haven't tried out either hodlhodl or bisq though so I have very little to say about them until I do. Centralized exchanges are ahead of DEXs but that gap wouldn't be there for long. More innovative DEXs or even upgrades of existing ones will help bridge the gap.
Uniswap's V2 has been a huge success but they would be releasing V3 soon around the same time Ethereum 2.0 would go live.
Liquidity providing is not really as big of a deal as it used to be, volumes are not that bad in dex places and people actually trade their coins quite easily, tokens that failed to find any volume at all and have been troubled with finding places to get listed all got here and just asked people to provide liquidity and now they are trading like nothing before.
The thing is, if you are already big and do not need these type of things, you do not care about it and maybe you will be listed or maybe you won't, you already have high volume and liquidity so why should you care, so some tokens/coins do not care about DEX since they work fine with CEX anyway. If big DEX places like uniswap could find a way to get them as well, that will actually change a lot of things for their future.
