I can't see any great issues using any of those. Just with the second mod, is your issue more that you don't want to level too fast or you're using it as more of a roleplaying thing in that your char doesn't know everything? If the former, then you can tweak the values in the ini for the Uncapper mod to not give as much experience for things like Smithing etc so that skill levels slower. If the latter, then go for it.
