Yes, unless you are building only on a mech, you don't need an ohm's reader.
I technically don't "need" toilet paper either we get plenty of junk mail. My ohm's reader is the technical equivalent of TP, because a) it's a stable base and b) I build up to test
vaping on it so it's been leaked on a LOT more than my more expensive regulated
mods. So for me it has usefulness although I will say that is a lot to pay for an ohms reader alone you might be able to get a whole coilmaster kit for that price somewhere, which also has SOME usefulness to some people, I find mine useful although I don't use each and every tool.
Wicking is also personal preference. I happen to find rayon better than ANY cotton material and I did start with cotton, so I know the advantages for rayon (for me).
In case you decide to get interested in rayon (you certainly don't have to) well, here:

Good luck,
