Your ears adjust to sound, in the same way that your eyes adjust to light. The "shock" you are describing is accurate.
Think of being in a dark theater and that going outside to the sun, same shock until your eyes adjust, then it's just another sunny day.
It's not just you, it's just how your ears work. (Unless it's hyperacusis.... in which case that is beyond the scope of this post LOL.)
I would say try not to get caught up in the A B ing of profiles, with gear there is ALWAYS something "better" who cares!
What should matter is what sounds good to you when practicing at the time, or what sounds good in the mix, when playing with others.
Keep in mind these will quite often be two completely different tones.
