While what you say is true, there are very important differences worth pointing out; bitmine have demonstrated a working machine, have shown piles and piles of components (not just a few trays of chips), have known and trustworthy people working with them, there is no mystery about their incorporation or their funding (which is very significant),  there are no questions about their technical ability seeing that their self developed chip and PCB actually works (achieving that is quite something else than gluing a few third party PCB's in to an mATX case), etc, etc.

Also not unimportant, Bitmine published specs and they actually seem to have hit them dead on (a first ever for bitcoin asics?), while AMT deliberately misrepresented the specs of those very same chips. Bitmine missed their timing, but unlike AMT, its reasonable to assume they did not expect to, and unlike AMT (and HF, CT, shall we mention BFL?) they actually have a useful miner protection program that guarantees its customers a significant hashrate increase and/or refund policy, going as far as refunding 10% on top of the purchase price.

In short,  Bitmine customers that where promised delivery first week of January should receive ~50% more hashrate than they ordered, some even double their order, and apparently at the promised power efficiency. AMT customers will receive at best the nominal hashrate, at less than half the promised power efficiency and my guess is, long after Bitmine's customers. That is, if AMT customers receive anything at all.
