PG - thin, lets through the most flavor and the most of nicotine's TH and irritation, makes thin vapor
VG - thick, dulls/smooths everything PG lets through, makes thicker more persistent vapor

Your vaping method may work best with particular ratios.

You can use any ratio of PG/VG with an atomizer as long as it will flow into the atomizer (you may need to thin very thick juices with a bit of distilled water or edible pure grain alcohol).

Stuffing type cartomizers can get sluggish if thick juices are used. I get the best continued performance with thin juices of 20% or less VG.

tanks and reservoir cartos like 20-30% VG though other thicknesses may work, 100% PG may leak more,

Most methods suffer from juices that leave a lot of flavoring sediment (often these are darker less-clear juices). This will degrade the performance of both atomizers and cartomizers

So if you're someone, like myself, who cares more for TH and flavor and not vapor, what's the point of having vg?

Oftentimes people like at least some VG for the "lung hit", the extra vapor production adds something for them.
Myself, I can vape anywhere from 0PG to 0VG, and do so, since I DIY and make some liquid that I share with others.
Some people are sensitive to PG, others are sensitive to VG, reactions ranging from general irritation to breaking out in hives. (Hives are an edge condition, not common, and at that point it is also at least moderately possible that a person may be allergic to a given flavoring, rather than the PG or VG).
A nominal 80% PG, 20% VG is pretty popular, a nice mix of PG and VG properties. For myself, less concerned about TH per-se, and since I use a mod that cranks the power (inherently more TH), I tend towards 65% PG on my own liquid; too high on the VG and I feel slightly sluggish when running (it's my personal perception, not necessarily the same for anyone else), though I appreciate a decent amount of vapor.

If you're not really worrying about a cloud, then all PG is what you need to stay with as long as you aren't having any problems with it. I like some vapor so I tend to go with 30-40% VG in my juices.

If I didn't care about blowing the O's, I'd be happy w/ 100% PG.
100% PG vapor disappears after deep inhale unlike VG mixes.

Before I bought a gallon of PG, I vaped for about a year w/ only VG, H2O, PGA, nic, and flavors.

You can get massive TH and good flavor w/ VG mixes (no PG); just adjust nic and flavoring.

If you don't care about vapor production then 100% PG may be the ticket.
