Depends on what you want to do with them
Saul has potential superstar and Victor allstar, so Saul has a higher ceiling as Victor.
The potential cap for both are the following
allstar : 40-65k
superstar : 125-145k
Regarding you situation i would say you need a good/ versatile role player so you could go with both of them and forget about their potential limit.
What i would definitely do for both is increasing their secondaries, and as quickly as possible. I would give both +- 2 pops in IS, in rebounding i would go for 7. And well for ID they have a huge differential, I would try to get 10 there so you could let them play PG/SG/SF.
Regarding their main skills i would make Victor my main traine and Saul my second, if you train 1 position you can give 3x48 minutes so it should be possible to train both equally
I hope i could help you :)
