Yes, agree, different needs...great that we have so many equipment choices available!
The main value in a streamer for me over bluetooth is, frankly, power savings for my phone when listening to Spotify in rooms other than my main workroom system. I can use the phone as control but the streamer is doing the "work." I still use BT occasionally on my dining room amp (SMSL AO100) and upstairs bedroom (currently with Fosi BT20a MAX). Both of these BT connections are good and the sound quality "good enough" for casual listening. We are in a 1916 home so many rooms, no easy way to do a multi-room single system, so I have a lot of separate setups.
I don't use PEQ, if Fosi does release a 10-band EQ on the S3, I will probably adjust the EQ for the living room a bit, but my rooms don't require a lot of EQ. (Good speaker placement clearing furniture, I don't use subwoofers, floors are carpeted and there are draperies, so not a lot of hard, bouncy surfaces.)
