I guess it all comes down to what you want from your Amiga. The a3k/a4k option is obviously more powerful (even vs an a1200 system upgraded to the same specs), and has the advantage of easier access to rtg/rta, whose influence and speed gains are quite substantial vs aga. The difference really is like chalk and cheese, not just in the potential graphics quality, but the speed. Granted you lose aga with an a3k, but Id take easier, non hacky rtg over aga any day if it was my only amiga.
