Matthews, Modern, and Avenger are the three most commonly used. Avengers are very heavy and have a few extra features like rubber on the knobs. Matthews are pretty light but will last longer than you will. Modern will also last as long as you but will degrade in appearance and look like trash after the first day (I don't know how that happens).
Personally, I have Avengers because I can get them on Amazon Prime next day. I always seem to need another C stand immediately. When working on set with rental gear it's always Matthews or Modern.
PS Make sure you know how to safely use the c stand. There are several good youtube videos. It's very easy to create a disaster with an improperly set cstand (ask me how I know). And you 100% need a sand bag for every stand you buy. Don't skip that step (trust me).
