The Amiga had Amos and Blitz Basic, they were pretty good too. It’s not where I started, I had a Spectrum +2 first but I certainly learned a lot there before graduating to Matt Dillon’s DICE C compiler.
BlitzBasic was insane! I remember writing games on paper when I was ~13 years old whenever we were driving on vacation, just to type all the code into the computer as soon as we returned. Of course that contained dozens of syntax errors :-)
The Amiga also had a Microsoft BASIC at some point (with custom additions to target the Amiga's specialized hardware and windowing environment). It got replaced by AREXX (a version of IBM REXX) starting from Kickstart/WB 2.x.
I loved AmigaBASIC. It was so futuristic after cutting my teeth on a Commodore 64.
I was so bummed about the move to AREXX. It was much better in many ways, like interacting with the system or other programs, but not nearly as good for writing actual code.
