My whole thing about pros for Side-view...you get a little more feeling of depth for the characters in terms of the screen, you can actually see how big the characters are compared to a boss, and you can do some really neat shit compared to the DBS (I plan to EVENTUALLY convert CF to SVBS again, but not until either I can supply my own art or I find a person willing to sprite the sideviews, and get all my systems compatible with an SVBS, and possibly an RTAB or TTB (Timed-Turn Battle, look at Final Fantasy X, each action can affect the turn order).
ABS is neat in the fact in that you've gotta resist the urge to be "impulsive" and keep your cool under pressure, for one slip up and BAM, you die! I usually like the ABS system in Action games (Castlevania being one of my all-time favorite series...I got addicted to Final Fantasy IV and Super Castlevania IV at the same time as a kid).
All in all it's a stand on what you're looking for...SVBS is more of a visual flare while ABS keeps players on their toes.
