The only one of those you lose with sideloading is the "Beyond The Book" info, and most books don't have that anyway.
Advanced font options work the same in ePub and KePub, except that the KePub reader has a bug that shows up at very narrow line spacings, whereas ePubs work perfectly at all line spacings. Edit: And the adjustable weight/sharpness works for both OTF and TTF fonts in KePubs, but only for TTF fonts in ePubs. Most of the built-in fonts are TTF. It makes no difference whether the
books are siideloaded, just whether the
fonts are sideloaded.
ePub text layout is more sophisticated than KePub: The ePub reader supports OpenType kerning and ligatures, and has better hyphenation and justification algorithms. The KePub reader supports "old-style" kerning (which most fonts don't have, but you can add yourself using fontforge) but not ligatures. Edit: But the KePub reader supports hyphention of left-justified text, the ePub reader only hyphenates fully-justified text.
I don't use collections, but I think they are the same for ePub and kePub, you can manage them on the device or using Calibre. The only difference is that sideloaded books don't sync their collection status to the Kobo server.
