PVC will last longer and vinyl tube is easier and quicker to run... Gonna be a personal choice on that one! Cost is probably about the same if you Sat down and did all the math.... Gonna have to be a personal choice on that one!
Run it in vinyl then, it'll be quicker to get it stretched out and going. You can also roll it up out of the way when not in use. Why only 3/4 inch drain? I would have gone with 1.5 or 2 inch so it doesn't take all day to do a WC.
