Welcome, your message is inspiring and optimistic! I'm glad you have two ebikes that combine to suit your needs. Just a couple of points of clarification...
First, nearly all Bafang systems come with throttles, hub or mid-drive (especially DIY kits). "Mainstream" ebikes with Bosch, Shimano, Yamaha etc. systems, however, never come with throttles.
And the difference between mid-drives from Bafang and Bosch etc. is as significant as the difference between hub and mid-drives, IMO. The mainstream motors are definitely intended more for cycling enthusiasts, as they provide a more "natural" assist.
Second, I appreciate that for some, a higher price doesn't mean a particular ebike will serve them better. To say "Price does not mean it is better if it costs more," however, is a bit of a sweeping statement.
I've gone through a few dozen ebikes and 10s of thousands of miles since 2015, and my experience has been that paying a premium for higher quality is entirely worthwhile, especially for eMTBs on technical trails, frequent several-hour touring rides, and/or the best overall performance.
I'm fortunate to not need a throttle (yet), as I'm a lifelong cyclist and always want to pedal. I do have developed knee and hip issues, as well as chronic Lyme conditions from multiple battles with the disease since 2009. Just before I got my first ebike, I was diagnosed pre-diabetic, but being able to ride again has been my remedy.
Meanwhile, ride on!
