I am currently using a low-profile mechanical keyboard - Redragon K621 TKL with red switches. It is my second mechanical keyboard, the first one was the cheapest TKL I could find to test whether I even liked mechanical keyboards.
Chose this model as it was significantly cheaper than the generally recommended Logitech low-profile option that costs around 200 usd. Checked out the Corsair as well, but I think was turned off by some bad reviews, and it was more expensive as well.
I chose a low-profile as it is easier/faster to type on it. Especially coming from using laptops exclusively for many years.
Though I think I preferred the brown switches, unfortunately, this keyboard only comes with reds.
