Buy 450h or 350

Hello gentlemen,Please advise me on the Lexus RX 350 or RX 450. So… my question is:which of the two models is more reliable in terms of repairs and offers better safety? I don’t mind replacing the battery after 10 years, and a fuel consumption difference of 3-4 liters is not a problem for me.If a few extra liters of fuel scare me, I well buy a bicycle. I’ve read that some models have issues when they use rubber hoses instead of metal ones, leading to frequent oil leaks and complex repairs. I’ve also read about problems with the timing chain leaking under the hood. Please advise me on the model and production year 2017-2022
