Apart from the CP1600 been a good CPU to learn Assembly from. The INTV is more of a striped down version of the CP1600 when you see instructions take up to 10 cycles and more compared to the CP1600, missing instructions present in much older CPU's and in the CP1600, etc...
That said, the INTV can been or is a good entry point to learn low level programming from. But the winner in the 'easy to learn' department I most say, it's the DreamCast's VMU with it's little POTATO CPU . Not pointing CHIP8's due to it's "virtual" nature.

The only thing the Intellivision can do and the NEC PC Engine can't is the fact the Intelliviison can scale sprites up to 2x horizontally and up to 8x vertically, something the PC Engine can't do without using multiple sprites. For everything else however, the NEC PC-Engine is much superior. The PC Engine has 16 palettes, each with 16 colors. In that aspect, it is much superior to the Megadrive or even the SNES. However, there are only 512 colors to choose from and there's only one background available : that background can't have more than 16 colors. (Unless you use some trickery of course) 8k of RAM is really not enough for a 16-bit game. It reminds me of the Colecovision, which had 1kb of RAM but 16kb of VRAM !
