Best for mostOxford (Luckhurst) · 2011
Roger Luckhurst's Oxford edition is the one I'd start with — the full 1897 text plus genuinely illuminating notes on the Victorian anxieties the novel runs on: technology, empire, disease, sex. Inexpensive and well-introduced. This is where I'd start.
Best for studentsNorton Critical · 2021
The Norton Critical Edition surrounds the text with sources, contemporary reactions, film history, and modern criticism. If you're studying Dracula or want the scholarly conversation around it, this is the one. More than a casual reader needs.
Best valuePenguin (Hindle) · 2003
Maurice Hindle's Penguin edition is a clean, inexpensive read with a solid introduction. Fewer notes than Oxford, but everything a general reader needs, and often the cheapest in print.

FreeFree (public domain) · 1897
Dracula is out of copyright, so the full 1897 text is free — Gutenberg, Standard Ebooks. No notes on the Victorian background, which adds a lot, but it's the whole novel at no cost.
