What is the reason why you don't like them?

They are actually better because you only have to take a look at it to see if it's blown. With a blade fuse you either need a tester or you have to pull it out to check it.

The original aluminum ones can corrode but you can just get new ones that don't do that. Or clean up the original ones, put some conductive grease on them and you're good to go.

Swapping a fuse box is not an easy or simple task. And knowing that most running w201's out there have other issues going on with them then if it was my car then I would focus my time and energy on something else.
