At the lower stakes where there are so many different types of opponents, stats are huge. There are so many mistakes that people are making and unless you only 1 table and take notes on everything, you'll never remember it. The other thing that is important, you actually play a lot of the same people daily and might not realize it otherwise. You definitely don't need a HUD, but at the very least, make sure to take detailed notes on your opponents, especially when you get to see their cards.
