Reviews are like bikinis they show so many things but hide the essential.
You simply can't rely on just reviews for choosing or buying your lens, it's not only about what suits your needs best but also how important the differences are.
Let's suppose you are considering a standard lens for 7D MKII compare the reviews of Canon 15-85 and 18-135 STM here, when you check sharpness distortions , vignetting, etc you do have numbers, but how much are they useful for you ? can they help you make a choice ?
Consider now 15-85 vs 17-85, despite the focal length advantage you can see the catastrophic CAs and distortions on 15-85 and hence the review here is more helpful.
You can say it is because 15-85 and 17-85 are more comparable that's why the review helped, but can reviews help you decide between getting Canon 16-35f4 IS 16-35f2.8 MKII and 16-35f2.8 MKIII with extra cost ?
