Just keep using oil based and your results will still
look great after many years. Water based is moisture
sensitive and nowhere near as abrasion resistant as oil
based poly.

In my experience there is little to no difference in lifetime of either oil
or water based.
I've even used iit on my cement garage floor for where the tires track to
make it easier to sweep out the winter sand & salt. It lasted longer, if
anything, than the previous oil based.
