The 30 minute flight does offer some nice scenery when the skies are clear. However, I would expect overcast conditions this time of the year and limited sightseeing. Don't expect anything more than a beverage. Unlike Alaska, Horizon still offers complimentary wine. The Dash-8 does not offer first class seating but I think this is the most comfortable prop plane in commercial service. It always entertains me to be seated next to the high-fuselage wing and watch the landing gear extend. It's pretty cool to see the landing puff of smoke up so close. The only obvious different difference between the 100, 200 and 300 series is the lengthening of the fuselage.
AS and QX do not share gates but QX flight are right next to the AS gates in the C terminal. Alaska also operates out of the D terminal. Rather short walk between flights. The Horizon folks usually have fresh coffee and newspapers available in the waiting area.
