Flat iron 2c/3a thin hair

Hello! I’m very indecisive when it comes to choosing my hair tools and I tend to research a lot and then I get confused! I thought it would be best to come on here and ask other people there are thoughts and opinions on what they use! I have thin 2C/3 a hair and a lot of it I’m prone to frizz at the roots and my hair has a hard time holding heat.

I’ve been looking at the babyliss pro nano titanium, hot tools pro artist black and gold, and the bionic (probs won’t go with this one bc of price and I don’t use a straightener all the time)

Let me know your thoughts and opinions! I want something that will last me at least 5 years
