The Redwood matches your clubs' meter speed while the Daytona is a little slower. Aside from that the only real differnce is in the scales. The Redwood has a 45 ft scale where the Daytona has a 60 instead.
Given the convenient 45 scale and matching meter speed I would suggest renting the Redwood. One thing to keep in mind is that you are looking at putters that don't forgive as much as you're used to. Neither one of them is going to make you a great putter instantly and a lot of people that have tried them gave up too early because of the learning curve. The curve isn't that big but throw a faster meter and tighter forgiveness together and you can get frustrated real easy.
What I like about the Redwood is that it is very accurate when you use what WGTNiv laid out in the Putting Tips where you calculate the value for each putter move on the swing. Give it several rounds before you make up your mind and if you like it but want a slower meter you can always go to the Daytona. Either one is really going to help you. GL
