I regularly use Raydium & Orca, apart from those two DEXs there are no other DEXes on the Solana network that I use. For me, only the two DEXs that I mentioned make me comfortable in trading and also both DEXes have great fundamentals & adoption. Maybe the list from Alchemy can provide a little explanation about the DEXs on the Solana network, you can read it here: https://www.alchemy.com/list-of/decentralized-exchanges-dexs-on-solana
