If you want to squat big, you should give it a try, if you want big legs, high bar is fine.
Personally I switched when I reached a plateau on high bar and wanted to simply try low bar.
Heavy high bar felt really bad on my neck too.
First about bar position, it may feel weird at first but you just need to find the correct adjustment, one big tip is thumbless grip for your wrist if you can't hold the bar without wrecking em.
The big thing with low bar squat is that more muscles are engaged and the lift feels more easy. High bar really emphasizes on quads while all your posterior chain will be engaged on low bar squats.
