Lately I've been using ImHex a lot [1], it's a modular hex editor that has schema files for different file formats which comes in handy when you work a lot on reverse engineering memdumps from firmware flash files.
It also has fuzzy finding features of known file format headers, so it can also be used to recover things from dd images, though it can be laggy sometimes when walking through a couple GBs of data.
