There is a good thing about Bound Weapons, at some point they can cause SoulTrap and they do grow stronger, but they are still weaker than any crafted weapon of that level. Bound weapons look like Daedric gear, but believe me, I think those are second-hands or even third hand rate when it come to damage.
Weird thing is: after I checked my Bound Bow stats at the item menu and comparing it with the regular Daedric Bow, the Damage for my bound bow is 82, while the regular Daedric Bow is only around 46 damage. And since my smithing skills are still too low to maxout Daedric weapons, I'm relying very much on my Bound Bow right now.
Plus, Bound weapons look cool and sparkly and it cements the roleplay for my Breton Planeswalker. The only weapon I try to equip is the Blade's katana looking sword which looks good when I dual-wield it with a bound sword while wearing a Penitus Oculatus armor. haha. Besides after reading some of the comments, it seems that having pimped out enchanted weapons breaks the game by making it too easy, so they crank up the difficulty level. Which kinda make your followers a lot more useless than they already are.
But I enjoy having my homies tag along as we stroll around pimping it out on skyrim. And I enjoy aiming headshots past their ears as I aim for the enemy's head. It doesn't really make things any easier for me, but it certainly makes it oodles more fun..
Besides, I lol each time I send a follower to go trigger a trap.. haha, fun times.
