On Swiss International Airlines' LX023 JFK-GVA Business Class, Seat 4A, may I ask what the quality of the flight and comfort please?

Their First Class is much more costly, and the next best is this Business Class and in that specific spot (just behind the First Class cabin but in the same section) for an extra charge.

I'm wondering if it's a big step down from various other First Class trips to Europe or is it "almost as good"?

I've never sat in a Swiss flight with those "put your legs in a hole under the seat in front of you" type of sleeping reclining seats.

Is their Business Class at all good or very good or close to First Class? Or is it a huge step down?

Thank you.
