I do wordle, strands and, when available (once a week) I do the midi.

Wordle and strands together usually take less than 5m. The midi ranges from 3m30 (my best time) to ~12m (my worst).

Not done Letterbox, Pips and Tiles, but I figured that all their puzzles are at the same level of difficulty.

It's interesting, to me, that (from my reading of the paper, which was very quick) they they consider it hard/easy based on a sort of brute-force attempt to find all the answers.
