I am just beginning. I have an old nylon string classical guitar. As a brand new guitar player I would like to know what guitar would serve me best to create better habits in the long run. I have looked at steel string acoustic guitars and find the main differentiator between that choice and my classical seem is

1) The classical has a wider neck

2) It doesn't have the fret markers that a typical acoustic guitar has.

3) I like the sound of the nylon strings over the steel strings, but my only concern here is whether the feel of one over the other will teach me better habits.

So,specificaly with the end goal of creating better habits with an ultimate ability to play any type of guitar when I am more experienced, what type of guitar is best to learn on?

Thanks for any feedback!!
