I love my Guv'nor V1 a lot these days, it's got that raspy Marshall vibe.
Other than that I prefer any OD on the grittier side, good experiences here with boosting input stages using
Fulldrive OCD (fat),
MI Crunch Box (fluid and cutting),
RC Booster (clean and punchy with loads of overtones),
Box of Rock (no sustain but great crunch),
Fulltone Soul Bender (fat, creamy, violiny).
Listening to this forum I guess you should consider the Blackstart HT series too.
