JBL Bar 2.1 vs 3.1 Comparison: Sound Quality, Performance & Usage (Movies, Matches, Music)

After reading a million threads in the forum, I decided to go with the JBL Bar.
For some time I was decided on JBL Bar 2.1, but I have a friend in the RTV store, so I have quite a discount on this equipment and here I look more and more towards the JBL Bar 3.1.

Have any of you listened to both live and can say something about it?
In JBL 2.1 we have a 200w sub and 2 speakers each 50w, and in JBL 3.1 suba 300w and 3 speakers 50w, but is it really listening to the sound?

The soundar will be used: 50% movies, 30% matches, 20% music.

You will definitely hear lower bass registers on a larger set, because mainly the subwoofer is definitely bigger there.
It's best to go to the store and ask for a demonstration of both sets.
It may turn out that a smaller set will meet your expectations successfully.
Don't listen to the "sellers"
