Generally, yes, but in this case no. It's not a matter of opinion.
Aether currents could only serve 2 purposes: 1) encourage exploration outside of the MSQ path or 2) gateway so that you don't zoom across the map while doing MSQ
Except 1) is done a lot better with Sightseeing logs, hunts, job/role quests, sidequests, beast tribe quests, etc. and Aether Currents don't tend to be too far off from the MSQ path so you don't end up exploring much (best examples would be Churning Mists were the entirety of the top of the map is left unexplored)
And 2) you can achieve exactly the same result by unlocking flight at the end of the MSQ for a particular area, which is kinda what currently happens since a most of zones in Stormblood and all in Shadowbringers have the last MSQ of a zone giving you the last Aether Current.
So as you see, Aether Currents are a waste of time due to the facts I've described. Facts are not opinions.
