There is no need to use the Glacier Express from Brig to Zermatt. Most Zermatt line trains are now operated by the latest Electric multiple unit trains. They have big windows (with some in 'Panoramic' style anyway, and you can get on any regional train you like, it is no slower because the line is mainly single track. They run every 30 minutes.
I recommend using regional trains on the MOB (the real name for the Montreux - Zweisimmen railway). Again, this gives you the flexibility to get on a train at whichever time suits you.
