I've switched from ace-jump to avy with De Bruijn hints; it shows all the hints at once rather than in sequence, even if the hints overlap with one another.

The downside is that, sometimes, the hints are longer, but I've found it faster to know right away to type "wxyz" than to receive "w", "x", then "y" one at a time.
