I agree. For hard product it depends on the jet, which can change. I did a RT with Delta out and Virgin back (pre Covid). Both had those skinny slanted herringbone seats which I did NOT like. You should look up reviews and seating charts for the possible jets. I will say, at the time, Virgin had very good flavorful food and a great lounge in London. I have avoided BA out of Nashville because of the shared foot space on the jets they use from here.
