I had a 2019 Limited with the hemi. It served me well for 117k miles, but then started throwing check engine lights. I was told the code could have been anything from a sensor under the intake manifold to a wiped out cam lobe. I traded it in for a 2025 Limited with the SST HO engine. Other than missing the hemi rumble (my old truck was straight piped) I'm completely happy with the new truck and the 6 cylinder. It's stupidly fast, comfortable and has all the options. My dealer even covered the powertrain up to 100k. There have been reported issues with the new truck - mostly electrical stuff, but that could happen with either engine. Drive both and pick what you like.
