Yup, was going to say the exact same thing. Aeropress for simplicity, or pour over for the experience. A French press will be inferior to both in the ways I mentioned; It’ll be less simple than an aeropress, and won’t be as good as a pour over.

The aeropress extracts completely different from both, I may append. It is the only option where you can actually taste some of the flavors of better beans if grinded freshly.

It also resembles the brewing steps using a portafilter machine.

I used all methods each for a few years. Obv. I settled on a portafilter machine because everything else is inferior by far - anyhow my experience:

The french press is the option to pour multiple coffes to different people. Everything else will taste worse over time - regardless of insulation. Glass: Cold fast. Insulated: Overextracted. Glass kept warm: burned.

A pour over is awesome for a single coffee. Haven't tried them with stainless steel filter. But this should even improve the taste.

The aeropress is awesome. I use it with an stainless steel filter as well. The taste is way better then the other two. You can make multiple cups pretty fast, since you only need 30-60 seconds if the coffee is already grinded and the water hot.
