The only game on Vita that has unbearable load times was Wipeout 2048; they did have the intelligence to patch it, though.
Uncharted Golden Abyss has a hefty minute or so start screen load, but after that I don't recall seeing load times at all. Rayman's load times were short, and they let you hop, skip, and jump around a minimap while you wait the 10 seconds or so per level, which is nothing. MLB 12 the show has hefty initial load times, but beyond that nothing serious. Little Deviants was practically nonexistent. oh, ModNation Racers was kinda hefty, load times kinda sucked on it (Racing games seem to be the issue here.)
As for Download games, Sumioni was longer than I wanted to wait, but super stardust delta and Mutant Blobs Attack both had like no loading times.
So I'd say the ratio is about t he same on the Vita as it is on the Wii, PS3, or 360.
