Nothing phone 2 or 2a plus?

I think that i decided to get a nothing phone for my graduation instead of an iphone.. tell me if i made the right decision, anyways. Is it worth getting the 2a over the 2 for the bundle? I am gonna use the phone as my main phone. I PREFER THE COLOR BLACK There is a 2a plus that has an additional accessory which is the cmf neckband, how is it? And is it worth getting that bundle instead the other one just for the neckband? (I prefer black and the bundle with the neckband doesnt have that color sooo.. ill prob not get it but i wanna see what do you say guys! Also one more thing what are the BIG differences between the 2a and the 2a plus? So excited to try a nothing phone VERY SOON 🤍🙏
