It's difficult to specify a favorite because there are so many elements to consider.
For workmanship, it's the American Eagle. There was an extraordinary amount of hours put in to create one, and they used the finest materials. The acoustic and amplified sound is as good as it gets from the 17" custom carved archtop by Heritage.
For elegance in a standard sized full archtop, it's the Johnny Smith. Golden Eagles are damned close.
For big sound, the Super Kenny Burrell or Super Eagle.
For great sound in a more comfortable archtop format, it's the Sweet 16.
For the all around archtop workhorse, it's the H-575.
For comfort with a great electric sound, it's the Millie. I like the Millie Eagle 2000.
For great electric sound then comfort, it's the Roy Clark. This model has all the good of a 555 with more top territory to show off the wood.
For a best buy it's the H-150. The H-137 is another if you want P-90s.
