When Powerboat Reports tested them, Fabula's Honey Teak came out on top, followed by Smith & Company's Five Year Clear. The latter has been discontinued and*Smith now recommends Epifanes Gloss instead.
I've been using the Honey Teak for 9 years now and love it. http://www.fabulainc.com/
*You can read the test results from Practical Sailor and Powerboat Reports on their site.
