Welcome to MySwissAlps! Indeed you can't go wrong on either. Plus, they're all centrally located and within walking distance of the Interlaken West and Ost train stations. The Lindner could theoretically be slightly quieter since they have a front garden, so a bit farther away from the main road. But not much I guess. Perhaps look at prices then? If you click the links in your post you can compare prices from several booking websites.
Enjoy your stay!
