The Pyoro one is just the two Pyoro games from Mega Micro Game$ bundled together and Paperplane had an added Time Attack mode and two player mode, I never played the latter, but I'm assuming it's the same as the Mega Party Game$ one.
I do think that both are nice to have, but nothing outstanding, getting Mega Micro Game$ gives you way more bang for your buck, but it is a way to play those two games on DSI/3DS and that's nice.
Also fun fact the appearences of the Ware cast in DSI Paperplane are based of Smooth Moves, that means Cheerleader Mona, and 18-Volt joining 9-Volt, also Ashley has been added to the game as well.
