A question for the ages: silicone or water based lub?

I like these in theory but changing the refills or even just pulling it up to see how much is left is a huge pain with these. The top always pops off which can become messy. Still use it though because it's still better than other travel options.

For trips is either carrying a bottle in a Ziplock bag or one small one-use small bags.
