For some reason I think of it as an older concept. Now Starbucks and coffee chains are popular.

Highlighting carlcook’s advice:
dissolve in cold water, ONLY THEN add hot water. The rationale behind it is that aromatics evaporate too quickly when the instant powder is infused with too/boiling hot water.
I would judge that pour over is higher tier. Search YT for vids, some people are sickly obsessive over how to do a pour. IMHO, pour over is second only to espresso.
Hmm. I did have a look.
I think you could divide extraction methods into pressurised vs non-pressurised.
Probably personal preference which is best.
