AFAIK, the STE can have 14MB of ST-RAM (i.e. GFX RAM)
.
The game has just been optimised to use a lot less of it. Just think about it, 14MB of Chip RAM would be quite the thing. We very nearly got support for 8MB Chip RAM, but sadly Commodore ended up not implementing it in AGA.

ST Blitter speed is dependend on how you use it. Apparently, if you use it properly and have BOBs that are 32 pixels wide or multiples thereof, you can get a throughput that is about the same (or even slightly higher in some cases) as the Amiga Blitter.
It's certainly faster than copying from Fast or Slow RAM using the CPU though.
Note: I am not an ST Blitter expert, I'm just repeating things I've seen on EAB and on YouTube - where talented STe coders have essentially 'tied' with the Amiga's Blitter speed for 16 colour low res screen modes.
Note 2: this speed comparison is valid for simple BOB blits. If you start using the tricks that Sandruzzo talked about, the result may be more in the Amiga's favour.
