Reviews seem good enough to my liking.
According to this benchmark, 150U is better than 1355u
HP pavilion plus with 7840U has better IO then HP aero.
Any other good offerings in your mind with 7840U?
Also, Are P series with good cooling available in non gaming laptops/work laptops?
I have doubts about that website but the Cinebench R23 numbers seem realistic.
It seems Intel 12th gen & later have better SC perf but multicore perf is similar across CPUs being considered, i.e i5/i7 U & older R7 7730U. Not sure of weird Geekbench numbers for 7840U but I have no doubt it is a step above any other U CPU from Intel in all respects except availability.
IMO get AMD as battery life is better as well although Intel did improve efficiency in latest CPU (core ultra) & AMD's Zen4 CPUs seem less efficient than older ones (78
40U vs 77
30U) but is still good.
Zenbooks are considered good, check reviews & check extended warranty prices as well.
Notebookcheck has some numbers:
