Can confirm. Traveling via public transport in Switzerland is remarkably uneventful. It's a stark contrast to my Eastern European home country, where it is a gamble due to a certain demographic's anti-social behavior.
I commute every day in Switzerland, and we have people blasting music, shouting, putting feet on seats, taking 3 seats etc, including in 1st. I actually stopped traveling in 1st, it could be more noisy and chaotic than 2nd and the price difference wasn't worth it.
