Yes, there is a right answer. "More is better", always, in everything you do. More RAM, more CPU frequency, more motherboard features, more SSD speed, more GPU power, more HDD capacity, more, more, more! Heh. Ok, too much coffee. My bad.
Anyway, back to the OP's original question, in all seriousness, the biggest determining factor here is what the laptop hardware supports, or is supported by, in terms of OS, BIOS and driver support. What is the full model of the laptop?
