I was writing some product reviews and found that articles, specially the long ones with multiple products/comparison-types are more effective and converting when you write in first person rather than third. But then I wrote a couple small articles where I used 'we'. I think 'we' imparts a sense of collective research and responsibility very quickly, even if there's no mention of a team on the whole website! On the other end, 'I' simply puts an idea of personal opinions. Both ways build trust, but I want to know which style you use more than the other, or that which one is better according to your past product reviewing experience?
