Valve stem seals?

I'm dropping in an 03' 5.4L 2V with 109,000 on it with excellent compression and am going to change out the valve stem seals first while still on the pallet. Who in your opinion makes the best VS seals, longest lasting? I see the FelPro brand says they're "improved design". What's the best for long term use?

Thanks.
