Brands I'd say Lane Limited, Mac Baren, Peterson, McClelland, Peter Stokkebye,, or CAO.
My go to aromatic is Lane Limited's 1Q.
As for suggestions:
Lane Limited- 1Q, BC-A, RLP-6, Black Raspberry
Mac Baren- Any of the Seven Seas line, plus Honey & Chocolate, Vanilla Cream (prefer flake over loose cut), and Original Choice
Peterson- Sunset Breeze, Connoisseur's Choice, Nutty Cut, Gold Blend, and De Luxe Mixture (also the yearly offerings like Special Reserve, Summertime, and Holiday Season are very good aromatics)
McClelland- The Premium Aromatics line is very good as well as most of their bulk aromatics
Peter Stokkebye- I enjoyed his Nougat and Cinnamon blends
CAO- I've really enjoyed Moontrance and Eileen's Dream (smoking Eileen's Dream as I type this) and I've heard good things about Bella Vanilla and Cherry Bomb.
