More importantly the firmware must be efficient and optimised. And up to date security patches. I have Samsung and LG that upgraded to later versions of Android but so laggy and buggy it's terrible! And they certainly provide new ROM once in a blue moon.
On the converse side, Amazon Kindle Fire runs Android 5.1 but it's so well optimised that it runs well on relatively poor chips/mem and security patches are always updated. Shows what good sw optimisation can do.
