Not comparable to any of them.
The Lite and SP both came near the beginning of the consoles life as a vastly superior upgrade fixing major issues with a price cut to boot.
Micro came when the GBA was already replaced (not that they were admitting that yet), actually RAISED the price back up iirc, and while not the giant hideous step back the 2DS is (it did lose original GB BC though), didn't fix anything that needed fixing.
The 2DS instead comes closer to the (likely) middle of the lifespan of the console, is the GREATEST hardware regression yet, and also the greatest price advantage yet (the other models don't fall to match it this time).
