I no longer really need a HWW since my funds are either

a) onchain in a 2of3 multisig as a vault b) in a lightning channel for spending

A HWW made sense when I was still regularly spending from a singlesig. Now I simply receive via lightning and when I have too much on lightning, I use a watch-only wallet to send the excess onchain.

I'd still recommend a HWW for beginners though.
