Chop first also saves a (movement) turn of the worker - so it gains one shield over using the BG. Of course this comparison is foul because in the long run a mined and roaded BG is more valuable / we would have to invest this worker effort later...
However even with chop first we can produce a single warrior first (using the BG at 2spt), so we won't completely abstain from exploration.
But as I pointed out earlier: I will only consider chop first, if our settler reveals no other BG on the river which of course is more valuable. With so few BGs I would gamble on finding one under the trees. This would be the real value of the chop.
But I might also hit for a long walk along the river if the area is so uninspiring...
