Do you use a bought processing kit or do you make up the developer solutions from basic chemicals? C41 kits that I have seen are expensive, which puts me off using them for B&W film.
If someone gave you a roll or two that you are just trying to use up, sure, break out the Rodinal and have fun or just take them to your local mini-lab and be done with it.
If all you shoot is B&W, a "normal" B&W film might be a good choice instead. The chromogenics though have some real advantages worth considering even if B&W is all you do.
If you shoot color and B&W C-41 rocks.
I think of chromogenic B&W films as one-color, color films, not as B&W.
One of the beauties of C-41 is that I can shoot a roll each of Kodak BW400cn, Ilford XP2 super, Kodak 160VC, and Fuji NPZ and develop all 4 different rolls in one tank, in one go.
If I tried to use one tank in one go to do a roll each of TXP, TX, TMax100, TMax 3200 I'd probably have a mess. So with normal B&W film I end up running most every roll alone or at best paired.
I started C-41 with this kit,
55fp475, which can technically do 300+ rolls. I figured if I got 50 rolls out of it I'd be happy and I did way, way more than that.
If you are going to do 50+ rolls in half a year this isn't expensive.
