"...I have looked into this and I still do not really understand the difference between these two functions..."

I think .write() is just sending the value as is, whereas .print() is converting the value first into its ASCII encoded representation before sending it as one or more values. e.g.

.write(255) is sent as a single byte:

255 or 1111 1111

.print(255) is sent as three ASCII encoded bytes:

'2' '5' '5' or 50 53 53 or 0011 0010 0011 0101 0011 0101

.print(255, HEX) is sent as two ASCII encoded bytes:

'F' 'F' or 70 70 or 0100 0110 0100 0110
