When I write こ and ご I tend to write them with a straight line at the top instead of with a tail like how it's supposed to be written. I kind of have trouble writing it the proper way without making it look unbalanced. Is my way of writing them still somewhat correct and distinguishable from other hiragana?
These are at least readable and distinguishable. Actually, some Japanese fonts have こ/ご similar to yours (i.e., no hook at the top right):
Still, it's not a preferred way of handwriting こ/ご. Fonts for printing do not always reflect how you should actually handwrite characters. Your こ looks somewhat childish or comical to me. I basically recommend you practice the proper way.
