Rubber coatings tend to harden or even shrink over time. They are easier to press in with less effort because the rubber deforms, I can often push them in with my bare hands. The rubber coated versions seal better in spots that have some corrosion, scratches, oil sludge, carbon buildup etc. I prefer this style for replacement when the engine or transmission is not disassembled, washed or being unable to use a proper seal driver or press.
Meatal clad seals are the stronger longer lasting version, they are less likely to pop out and seal better against the case by a stronger interference fit with the drawback of metal corrosion or dissimilar metal reactions if the seal coating is damaged. You should use a properly sized installation driver or press to install these straight and to the correct depth without distorting the seals outward metal face or the sealing lip will be distorted.
Some like to use sealants, I do not because the sealant may not bond to the case or the seal creating a leak, the sealant may not expand/contract at the same rate as the rubber or metal seals exterior causing a leak or even seal movement/looseness/dislodging. Lock tite for seals may be used to help overcome case damage or bore size irregularities to the available seals, thankfully I have not yet needed to use this personally...but life throws curveballs at every at bat it seems.
