If you want it slow --> choose Kali (unless Kali also supports the arm64 architecture and not only armhf the '64 bit' the Pine64+ is advertised with are pretty useless for you). And whether you need 4GB RAM is a question that only you yourself can answer. At least you're not able to use more than 2 GB since the A64 SoC used on Pine64+ can't deal with more physical RAM.
In other words: Kali will be available since every armhf Linux flavour will be available sometimes in the future (sadfully -- I would suspect some crazy mind will even give Raspbian with ARMv6 code a try). You won't see great performance improvements unless Kali adopts changes to support also arm64/ARMv8. But since Kali is just another Debian and Debian already supports ARMv8 someone a bit familiar with Kali will be able to switch from armhf to arm64 in the build scripts easily.
Again: That's not important at all. The magic happens somewhere else since without proper driver support for the A64 (and more recent kernel version) every Linux flavour on the Pine64 will feel a bit crappy.
