You are right... all the talk about which machine and configuration to use is pointless if the A2K is a 68000 with OS1.3.
If the A2000 is 3.0 or better, 030 or better, and you don't mind throwing $100 or so at it for a Picasso 2 or a Retina Z2 or the ilk, it is a no brainer to go with the big box machine.
If you are talking bare bones Amigas... the 1200 is the only one usable and even it is not going to work well if you only have 2 megs of ram. With 2 megs, even a TCP/IP stack is tricky to get working.
