Remixed or Classic Mode?

Coming from a Tekken background, 2D fighting games don’t make much sense to me technically. I’ve downloaded the Fighting Games Beginner’s Guide from the page of this site. I also downloaded Super Street Fighter II Turbo HD Remix tonight. Still in the beginning pages of the e-book. Does it matter which mode I play in this game? Remixed or Classic? Are the modes similar enough for the concepts in the e-book to apply to both?

Any and all insight is greatly appreciated. My intent with all this is just to understand 2D enough to get into SF locally with the new PS4 release.

IIRC, the only difference between the two modes is the balancing. There aren’t different concepts you need to learn when playing one or the other.
