PS3 and Xbox 360 are very tricky.
The GPU of the 360 was way better than the one in the PS3, but the latter had the Cell architecture which could help out and theoretically more than even the playing field. As this was very labor-intensive it wasn't done to the extent SONY probably hoped for. As a result third-party titles tended to look slightly better on a 360, but first-party titles from SONY tended to look even better.
As for the rest of the list, Mster System should be above Game Gear. It's the practically same hardware (both have the same Zilog Z80 CPU, the same sound processor, the same 8kb RAM/16kb VRAM and 32 colors onscreen, the only real difference is that the Game Gear has a larger color palette to choose from, but still only 32 colors at the same time on screen like the SMS), but the Home console outputs at a higher resolution (256*192 compared to 160*144), so the Master System should win.
