Since you’ll be using way less TP overall, go for the nice thick 2-3 ply with ripples it’s worth the extra cost.

Once you become a bidet pro and feel confident in your ability to be squeaky clean each time (I’m not afraid to go in there with some soap as if I’m in the shower after a particularly messy movement) you can opt for cutting up old undies and using them as reusable/washable towels to dry off with and stop using toilet paper all together.
