Congrats on your new purchase and welcome to AGF. I can't imagine that anyone here is going to advise you to practice on your least enjoyable guitar, regardless of price. If you enjoy playing the new Taylor more, then that's the one on which you should do your practicing. Once you eliminate the discomfort from playing a guitar you can focus on your playing technique and style. And if you really think that your new guitar is doing all the work, try putting it on a stand across the room and see how much music comes out of it.....
