I would choose marketing. You can get great PR and not generate sales. Marketing is directly connected to sales and revenue growth. PR is more "earned media" and how your story connects to a broader cause. Both areas should be included in your business strategy. I find that if marketing is done right you will generate PR. Also depending on industry many of the PR platforms are paid, for example in crypto and blockchain many press releases are paid placements. Even mentions in top business media can be purchased and therefore part of a marketing budget. Digital has changed the game. Think bloggers, podcasts, YouTube channels, IG, FB and the like. Schedule a call with me if you want specific guidance and tips in any of these areas. Good luck to you!
