LA Timing Cover Preference?

I need to replace the timing cover on the 318 in our W200. It honestly looks like someone tried to clean the gasket surface with a grinder. A buddy had a couple good ones lying around. One is a rear-installed seal, one is front. Both have driver tide timing marker cast in.

Do people have a preference on which one they like more? Aside form being able to theoretically replace the seal on one without removing the timing cover, is there any advantage?
