On the fence whether to flash or return for a different model

Partly not true, on stock, unrooted, I had pretty good stability, only complaint is how slow the slider on the lockscreen is. No other slowdowns and no battery draining. Though it was from an sbf...So it's still partly true, it's really inconvenient to have to sbf your phone to get the most out of it. Imagine how many things could go wrong for an average consumer.

If you are ok without Bluetooth or VPN (PPTP, openVPN works) - you will be perfectly fine with CM7.

D3 isn't as good as it sounds (I've got both). Considering there's no root for it (yet), I can tell you D2G with CM7 works faster and better than D3 as is...
