I can comment from no experience beyond basic knoweldge of looks, but what I will say on that note is that it, in my view, was one of the last fighters that looked like a fighter....big, deadly, powerful. More modern aircraft look too clinical, all very clean and kinda powerful, but the f-4 just looks like it wants a fight.
Does that make any sense whatsoever?
TO digress a bit, i've always loved the lines on the A7 Corsairs and A-1 Skyraiders, I think both have a short nosed, stubby but purposeful look that if i were an infantryman i'd appreciate!
