Assuming you are meaning the Dr.Schutz Medica and Secura products and not the 2 part polyurethane sealers.
Medica and Secura are about twice the price of Tight Shine.
Both are extremely durable with Tight Shine being the glossier of the 2.
The biggest advantage of Tight Shine is its rapid drying time
(unless you are on my course at Restormate when it usually takes about 2 hours while we all stare at it)
Medica and Secura will last about 2 years on a domestic as they are quite hard products.
Tight Shine will be the same but with need good maintenance and buffing.
What floor type is it, which room, any pets, is it well laid (can you see trowel marks, nail heads or floorboards undereath)
