You're comparing apples and oranges and the apple you're looking for will never be an orange. (i.e. Standard machines are almost always going to beat out portables: https://boffosocko.com/2025/03/21/standard-typewriters-versus-portable-typewriters-and-ultraportable-typewriters.)
The feel question is also going to be so variable across people's experiences (not to mention the condition of the machines on which they were formed which is a tremendous amount of noise in the secondary market) that you're highly unlikely to find what works best for you in this way. Incidentally, this is also a great way to end up with 30 typewriters and still be unsatisfied.
Your best bet for all of the variables you're trying to optimize for is to go to a shop with a variety of machines in good condition to try and purchase something you think will suit you best.
All this aside, I nearly guarantee that neither of your machines are well tuned, so you might consider looking into this for your Sterling: https://www.youtube.com/watch?v=OYOXgqiHBmg.
