Depends on weather you want to take the tool along with you in your pocket. I have both plus those already mentioned plus a few others. They all work, some easier than others.
Of the two you mentioned I like the Ace, does the job and easy to store in your pocket or pouch. I learned wood arrows do not like climate change even when sealed multiple times. The shaft tamer will take the kinks out of the most stubborn of shafts and is my choice for laminated hard wood shafts. A heat gun would also help much with straightening shafts.
