Of course it makes a difference. A massive difference. 1mm at the saddle can turn easy, smooth and fast into an unplayable cheese grater. With a proper setup no strings should cause any of the problems you describe. Sort that before wasting more $$ on strings.
Let me make sure I understand this right. Lowering the string height can cause the problem? Just asking.
I had the strings set sky high at the saddles, as high as I could get them. I was a beginner when I did that, and I did it because it irritated me to feel my fingers touching the pickups underneath. I did that on all my basses. Then I read various comments here, more-or-less criticizing setups like that. So, I dropped the strings down to "just above buzzing" height, and that's when the pain started up, but only on the J-Bass with the DR Sunbeams. I made the same adjustment on all my other basses (which all have stock strings) but they feel fine.
