Internal batteries on mods - Good or bad?

I bought two Innokin MVP 20W mods 5 or 6 years ago, and both are still working. Also have a Joyetech cuboid mini with an internal battery which is also still working. I wouldn’t use them as an all day device but they work great for a quick run to the store or tooling around the house. I do prefer a mod with replaceable batteries simply because I enjoy sub-ohming and internal batteries can’t keep up as long.
