Early Martins sound better to me than the new ones. I don't like the dreadnaught shape, uncomfortable and awkward, unlike a guitar shape.

Taylors sound OK but are too weak for me.

Guild's (the better ones) have a clarity of sound and are good for recording because of
their overtone control. Martins tend to spread.

Some guitars that don't necessarily sound good, they might be cheap, may record really well.

I am happy with my early Martin 0021. It has to be carefully miced to record well, though.
