Transfer out of the BB and into a bottling bucket. It will make life easier. Plus bottling wands fit nicely on bottling bucket spigots with a small of 3/8" tubing. The old BB racking adapters fit 3/8" but now the bigger ones fit 1/2".
Indeed.
The problem with bottling from a primary or secondary instead of using a bottling bucket, is that since you have patiently gone and let your beer settle and clear, in order to mix the priming solution and beer effectively, you would have to stir it in the carboy which would a) kick up all that nice sediment you have patiently let fall, b) possibly oxydize the beer.
It really defeats the purpose of both a long primary/no secondary or a secondary if you have to stir up all the nice sediment you patiently waited to settle just so you can have consistent carbonation.
With the gizmo on the bb, you are also going to have sediment right there, which will transfer to your bottles and give you potentially more yeast sediment in the bottle.
Of course if you are using prime tabs it really doesn't matter. But most folks bulk prime with sugar solution, rather than bottle prime, it's easier and the results are better.. Especially if you carb by style. BUT if you are doing it from a spigoted bucket, that you've let stuff settle in, all that trub is going to be coming out into your bottles again defeating the purpose of any clearing time for you beer.
Got 5 bucks? Go to HD or Lowes and get a 5 gallon bucket, but make sure the five gallon mark is NOT the top of the bucket. And get a lid. Then go over to the area where they have camping spigot or replacements spigots for coolers, and spend the other 2.5 dollars on a spigot.
And you have a bottling bucket.
Mine is the translucent Leaktite brand 5 gallon container with the gallon and liter markings from Homedepot. Make sure to get the lid though.
Here's a pic of mine from my bottling thread.

You can also make a dip tube like I show in there.
Oh another tip, which I learned AFTER I already cut the hole for the spigot, put the spigot on the side where the graduated measuring lines are, NOT where I did mine.
Makes it easier to see how many gallons you have.
Nowadays even the orange Lowes buckets are about $2.50 these days, and a bottling bucket spigot at a homebrewshop or is about the same so 5 bucks for a bottling bucket is about right.
(must be in the same spot as the blue ones at HD.)
