I have been using death company for kill Team at the local game shop I play at and they are really effective. Looking at your list it really depends on what armies you may or may not be going against. If you are facing a lot of armies where the best they can get is a 4+ save then i would suggest the power swords. However if you play a lot of other space marine players where everyone one gets a 3+ save the power swords are just wasted points. In my experience more guys is usually better in kill team. My suggestion would be this:

Death Company x8
-7 with chain swords and bolt pistols
-1 with power sword and bolt pistol

This list gives you two extra guys to either attack with or capture objectives with which can make a break a game when you are working with so few models. If you are looking doe exclusively Death company i say that might be your best bet, but if you have some flexibility. my personal favorite is this list:

Death company x5
-all with chain swords and bolt pistols
Assault Marines x5
-all with chain swords and bolt pistols

You get 10 guys with a lot of mobility who can do some real damage, and then when those final turns come you can jump pack onto as many objectives as you can and snatch up victory. Hope some of this helps good luck fellow BA player!
