Mount Hood or Jefferson?

Height and access
Mount Hood rises about 60 road miles east of Portland, and its standard climb starts at Timberline Lodge at about 6,000 ft, with about 5,200 ft of gain to the summit. Britannica gives Jefferson as 10,497 ft; the USGS figure is used here. The USGS rates the two very differently as volcanoes: “Very High” for Hood, “Low/Very Low” for Jefferson; the volcano page explains Hood’s threat level.
Which is harder
Climbing discussions tend to rate Jefferson’s summit as more difficult than Hood’s. That is a view from climbing sources, not an official grading, and Hood’s own route is “a technical climb” per the USFS; the beginner page covers what it asks.
Seeing both
Timberline Lodge lists views of Mount Jefferson from the top of the Magic Mile. The flight tour’s listing names Mount Jefferson among the peaks seen on clear days, and Amy, from the United States, mentions views of Mt. Hood and Mt. Jefferson in her review of the waterfalls and wine tour.
