Side-feed AB benefits over gravity-feed ??

I've been thinking about getting rid of my HP-SBS since I rarely use it and always ended up using the 2 HP-CS instead since the gravity cup just feels easier to wipe clean (especially when it comes to model master enamels).  I've searched for a good answer to the benefit the side-feed AB over a gravity-feed AB online for the past weeks and nothing really came up.  Just the common fact that you get some better viewing and spray angles.  I hardly ever found myself to use the airbrush perpendicular to sea level at all doing models and my painting canvas is always on the easel.  Also to really look from the very back of the airbrush, my hand ends up in a weird angle so I can't use my fingers as well anyways.  Meanwhile the design of the 1/8oz paint cup from Iwata actually have the bottom of the cup sitting way beneath the airbrush body, which in turn somewhat turns it into a siphon cup and requires a little more air pressure as opposed to the gravity cup.  Yet on this forum, I've heard someone saying that they got more control with a side-feed and was selling his CS to get a SBS.  Jeff Herne also uses his HP-SB and all.  I kinda liked the way i get to swap siphon/side-feed bottles on my SBS when I do my artworks, but since in scale models, you really gotta wait till one color to dry first to go onto the next anyways, what good is a HP-SB/SBS if I don't have a gravityfeed sidecup like those aztek ones?
