Lets get the facts straight. Both are great rods and you cant go wrong with either. The Savy series was the latest rod by Dobyns, and was brought about to compete in the price range of the Powell and others. It is not as good as the Powell rods. The other Dobyns rods are great rods and priced higher, and they are lighter. However this does not mean better, that really comes down to personal preference, as do all rods.
Also comparing thse lines to GLX or IMX and saying they are equal is true in some ways. I dumped all of my Loomis rods and went over to Powell and Abu rods. To me they (including Dobyns) are better then those loomis rods. Warranty is part of being a great rod, and Im sorry to say Loomis has fallen way behind in that area.
TO answer the original question, both are great rods. You really need to try em out and find out what you prefer. In my area we have demo rods available so you can actually fish them.
