As someone who has used both, if you really planning on keeping your car for a long time my recommendation would be Koni inserts. I have used Mychailo's springs, and they were a great compromise between handling and comfort but I bought brand new Subaru OEM (manufactured by Showa) for all 4 corners.

They stopped making "new" struts for a long time, so the ones you do buy as "new" have been sitting on the shelf. Both my rear struts went out within a year and a half. Check out mychailo's thread on the DIY Koni inserts, as it takes out most of the guesswork to a lot of the installation. Plus these are rebuildable with a lifetime warranty.
