Top 1 or top 2, maybe top 3 but meeeeehhh top 1 is more realistic.
Top 1 from the bottom is correct grammar if they were forcing the usage of the phrase you used with the exact same words. In this case "Top 1" would end up being a noun as they are quoting is rather than an adjective as you used it originally, leading to the grammar usage being correct.
Please learn english before talking shit about someone else's grammar 💔
