Hi acapote and Welcome to MySwiss Alps,
You can go either way.
Let's say you go for Zermatt first.
If you go Interlaken to Zermat via Kandersteg you will then travel on the Regio-Express Lötschberger train over the traditional, more than 100 year old mountain route, giving you a wonderful view along the impressive peaks and down into the Rhone Valley. It takes a bit longer but the more direct route between Spiez and Visp goes through quite a long tunnel so you miss a lot of the scenery.
From Zermatt you can take the faster route back up to Spiez and then head to Montruex via Zweisimmen on the Golden Pass Line.
Or go to Montreux via Visp and follow the Rhone Valley. From there you can still take the Golden Pass train up to Spiez and return by a faster route through Bern.
