threaded or slip bulkheads?

[Mylilreef]

i am getting ready to reseal my tank and buy the bulkheads for my sump overflows. just wondering if anyone has a preference for threaded or slip? is there any drawbacks to either one?

I would think threaded are better but that is just me.

Threaded for sure, can be reused at a later time if needed.

I used threaded bulkheads, but I neglected to put unions anywhere except by my pumps, so I'll still have to cut my piping if I move the tank or have any problems.

thanks for the feedback, sounds like threaded it is....
