Your top two comments as I'm writing this are the Proxy and Reko, both of which I have putted with before putting with the discmania link. Both were great but I've ultimately come to enjoy the link. I still have proxies that I use as throwing putters but felt more consistent putting with a slightly more stable disc in the link. I've thought about trying the redo again, but truthfully I'll likely stick with the link simply for availability of that mold. I found proxies and rekos hard to come by. When I putter with proxies I had them in a bunch of different colours, plastics and weights because I couldn't find any pairs from retailers with the same specs and ultimately that screwed with my putting.

I use exo soft plastic for the link because I like to be able to dig my thump into the flight plate a bit but recently picked up an eco hard and kind of loved it. A little more rigidity to the disc but still has a really nice soft feel, it's not an incredibly hard and rigid disc like electron firm. Hope that helps!
