Q990F
Value for movies and easy setup, but music falls flat.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I have the QN90D with the QS700F soundbar, and the difference between the TV speakers and Q-Symphony is night and day. But if you don’t have a good spot near the TV for the sub, you’re probably better off going with something like the QS90H. Moving the sub away from the TV can make the whole setup sound thin, at least that’s how it was in my case.
I paid less than that for a brand new Samsung QS700F. I’m very happy with it. Doesn’t come with rears speakers v it can add them later. I won’t though because my small room doesn’t need it.
Got the QS700F for €329 (NL) and i think it's quite good for the price. I saw that it should be slightly better/newer than Q600C, so perhaps that's a better option? I know that isn't going to make your choice easier haha.
I’m no expert but I am real happy with mine. Just as you say.
and probably the same Samsung quality of non-standard protocol and interop as their previous soundbars, where it wont talk properly to even samsung TVs, will randomly switch mode for no reason, randomly display either numbers OR +/- depending on its own whims and require rebooting every few days or it wont play any sounds
*Needing* a subwoofer to sound good is a deal breaker for me. I'm going to get a sub anyway, but if you need one to sound good, it means the crossover is going to be set so high the sub is filling out low-mids like male voices, which is far from ideal.
