Always the source...whichever is the source...unless...
Whichever one the pictures were taken on - use that as long as it's in good shape. Otherwise, use the other one.
I would normally say go with the slides, but that might not be the *source*. I have a feeling you had the pics taken with the negative film ("normal" film) then got the slides made for your slide shows...huh...slide show - with *actual* slides!
Slide film, a.k.a. "positive film", is some of the most exquisite film you can get pictures on. It is rather sharp and has a lot of richness in colors and textures...but it's also a very truthful film, which can be good or bad - if you set your camera poorly, your pics will come out like that and there's only a limited amount you can do. ahhh, I like reminiscing about analog visual media...at least my meager knowledge is occasionally useful.
Since you have both, you may as well scan them both in and see which turn out better. Be aware, some scanning systems do better with color than B&W (I have a roll of scanned B&W and there's tons of dust specs, etc. that turn up on the scan that are not there in the negative).
I'd strongly consider taking them to a *professional* photographer friend or nearby lab...or call them up and ask them what they think.
