I think there are two things that bother me. First is the shape of the bottles which makes them a pain to clean - they're slow to fill with water, slow to empty out, don't drain upside down without precariously balancing on a bottle tree, difficult to scrub inside. Second is that filling the bottles requires more than two hands as you hold the bottle, pump the siphon whilst holding it in the FV, clean up the drips, find somewhere to put the full bottles etc.
But don't let me put people off starting out in home brew! Honestly.
