this is all subjective stuff and most any fletcher will get the job done.
HOWEVER, my personal subjective opinion is that the ez fletch is anything but easy. it's a very different design that uses 3 integral clamps and that's where the problem lies - it's not very adaptive or positive with feather fletching, it was really initially meant for vanes, it will not offer the larger range of helical, offset and number of fletch adjustments (both three and four fletch - nor will it do 2 fletch, should you ever wish to test those waters) that come standard with any good single clamp fletching jig.
i humbly submit that you would do lots better with a single clamp fletcher, and not a bitz. any polycarb fletcher such as the grayling or bohning pro (about $32 for either) will work perfectly for more than a few lifetimes, and the intial cost is less than the ez and nearly three times less than a bitz.
while yer at it, if yer not already using fletch tape, add that to your buy list and fletch faster/easier than with glue alone.
