Both make very high quality driveshafts but I'd go for one by Tom Wood. Their pre and post-sales support is unsurpassed. I'd also firmly request either use Spicer 5-1310x u-joints instead of their house brand. Personally I'm on my 4th or 5th TW driveshaft over the past 25 years.
I'm with Jerry here! This is my sixth set of shafts from TW. They are knowledgeable, honest, service has always been fantastic, and pricing competitive. As stated, just be sure to ask for the non-greaseable u-joints. The greaseable ones don't get you anything, unless you live in a rust area. Then, you get a tub coated with grease that you put into the joint!
