I routinely use 2nd class, unless I am traveling near the main cities during commuter rush hours. And, if I am making a long trip...say Zürich to Locarno, or Geneva to St/Gall, I'll take first class for the extra room and, commonly. seats that recline a bit. ...I have long legs and a sore back..
I use a half fare card, so I can choose.
Probably, with a 2nd class Flex pass, you would be able to buy a first class upgrade for a particular trip, if you wished to...It works for the Swiss Travel Pass.
Arno would have to confirm, if that is not already answered in the link that he gave you.
