I wouldn't necessarily choose Jansen over Kirk, however preferring Jansen is hardly indefensible. Starting from 2021 when Kirk became more of a regular Jansen has actually outproduced Kirk in overall value on a rate basis. Jansen comes in at 3.96 FWAR/550 vs Kirk at 3.17 FWAR/550. Jansen has had a hard time staying on the field, but when on the field he played like a 4.5-5 WAR player in 2022, and sustained this type of production despite having a lot of starts and stops due to making several trips to the injured list. I think it's up in the air what kind of offensive player he eventually settles in as, but I don't think the power surge over the second half of 2021 and entire season in 2022 is some kind of fluke.
