I’m new to snuff myself but I’ll share what I’ve liked so far but look through the German brands first, as a bunch of them are shutting down this spring.
After that:

If it’s history you like, Samuel Gawith has the oldest piece of industrial machinery still in regular operation in the UK from what I’ve read online. I’ve only tried Black Arabica and Gin and Tonic but I really like them both. I’ll try more of theirs in the future.

Toque/Artisan/Otto – Lots to pick from and everything I’ve tried has been delicious. Ficus Rappee and St. Clements are my #1 and #2 out of the 9 I ordered.

Gawith Hoggarth SP – Pretty neutral but great tobacco.

WoS Tom Buck – Strong bergamot and my favorite so far by quite a lot. I’m going to buy bulk next time.

WoS Bee M. – Menthol and honey. Might be nice to switch it up from the more traditional medicateds.

I’ve only made 2 orders and been snuffing for about 1.5 months so my experience is VERY limited but that’s what I’ve been liking so far.
