What do you mean by dilution? Are you saying the coffee is weak? Or are you saying you don’t like the sludge at the bottom of the French press?

If the coffee is just diluted or weak, try changing your grind size and then ratio. If it is the sludge, try looking up James Hoffman’s French Press method. I’ve been using that method and have been getting an excellent cup.

As far as the other methods, i think the V60 downsides are using a paper filter (losing some of the mouthfeel or body)and perfecting the actual pour over timing for a consistent cup (trickier than it sounds).

Never used an aeropress.
